mer-love masterlist here !

any interactions with RIN are short and definitely not sweet. if he isn’t being harassed by any other mers that are interested in him, he normally stays around you because you “don’t bother him as much as the others do”. quoted by rin himself; which is considerably high praise coming from the rather aloof merman.
you probably first meet him simply because he got dragged by bachira or the like, but he’s not much of a conversation starter since he just sorta glared at you the whole time. it doesn’t get much better from that point onwards either, you’d think rin believed the world was against him by the way perfectly normal, well-meaning compliments are thrown to the side as if you’re insulting him.
with time though, he’ll start growing more fond of you! how can you tell? unless you’re freakishly talented at guessing people’s real emotions, who knows.
he (kinda) gets cuter in a way? maybe it’s just you being optimistic but you could’ve sworn that he has this look of pride whenever you choose to spend time with him over the other mers. like, of course you don’t want to hang out with weaklings like them or something along those lines. it takes a while but he’s noticeably softer with you than he is with his friends — he actually calls them lukewarm, but that’s just rin for ‘friends’ you think.
“Rin, ya there?”
He stares at you with mild disbelief, which almost makes you burst into a fit of laughter. “Since i’m very clearly here next to you, I think the answer’s quite obvious.”
You nod, grinning. “Thought you’d say that but anyways,” you say whilst reaching into a bag, “I wanted to give you a present! Take it as a token of my gratitude for you chatting with me.”
He eyes the object you give him coldly, but takes it anyway with a ghost of a smile on his face. How adorable.

SAE is someone very hard to come by, and even harder to start conversation with that don’t end in him just swimming away from you. if you thought talking to rin was like talking to a brick wall, just wait till you meet this guy.
he’s seemingly apathetic to anything and everything, incredibly blunt, and overall not a very nice guy. at least his lil brother doesn’t outright ignore you (he does call you an NPC and half baked though)! speaking of which, if you meet rin first you can definitely see the resemblance between the two. appearance is a main one, you would know those under-lashes from anywhere and now you definitely know where he gets the attitude from.
any signs of him ‘warming up’ to you are basically non existent. he’s as straightforward as ever and isn’t keen on the idea of suddenly being all over you like humans normally seem to do with the people they like.
to give credit where credit is due, he tries? even though he’s still a bit brutal with his delivery, you think he tries to avoid being so aggressive with his tone. he’s not exactly sugarcoating things, but simply not saying what’s on his mind as much as he used to. that whole spiel about if you’ve got nothing nice to say, don’t say anything, right? and besides, just him tolerating your presence should be enough for you to understand he’s trying to be nice (it really isn’t).
Sae has a talent for ruining any positive conversations with his honesty, the aftermath typically being him leaving the person or awkward silence ensues. To give credit where credit is due however, you also think he’s got a talent for somehow making people feel better.
He doesn’t sugarcoat things and while it can be harsh, it also means that compliments from him are genuine.
He listens to you rambling on about some annoying incidents at work, making the effort to nod every once in a while to remind you that he’s paying attention. “Sounds like something you can deal with yourself. There’s no reason to worry yourself about it, that’s a waste of your time.”

amidst a certain merman’s grumbling of someone called ‘KAISER’, you gain snippets of info that paint a less-than-flattering picture of the merman. he sounds like a major jerk. yet, despite his (isagi’s) colourful descriptions shall we say, you can't help but wonder if this kaiser fellow’s supposed villainy is just an exaggeration. but then again, to evoke such hatred from the usually amiable merman, he must be quite the character.
your first encounter with him is unremarkable, only seeing him as another mermaid who decided to show their face and you as some random human.
his curiosity is piqued however when he notices how fond the other merfolk are of you, and in typical kaiser fashion he’s determined to outshine everyone else. from your perspective, he’s just a weird dude. it’s as if he expects you to be grateful for his attention, even though it’s clear that he’s the one vying for your approval.
it’d be somewhat cute if it were anybody else, you think..? on him, it’s aggravating.
and yet, the more you pull away, the more determined he seems to become to disrupt any semblance of peace you have. he appears so often that you’ve grown to actually tolerate his presence and it even amuses you sometimes if the day is particularly boring. kaiser finds you just…okay (liar). he means- you’re nothing special so don’t get ahead of yourself but like, if YOU wanted to, he wouldn’t mind being with you until nightfall.
also don’t mention the sheer disgust and almost betrayal on his face whenever he sees one of your total losers of a colleague on watch duty instead of you. even worse if they’re partnered with you.
Judging by the very obvious glare Kaiser has on his face, you would say that he’s not too pleased with the sight of you and (coworker) together. Still, he could at least try be more discreet about it. You sigh as your companion only spares you a sympathetic look.
What’s annoying is that Kaiser occasionally glances in your direction — of course, whilst still glaring daggers at (coworker). Like he wants you to do something about them tagging along.
Having enough of it, you say, “Kaiser, you’re embarrassing me over here and yourself.” He pauses for a moment before simply turning around, probably sulking over the fact that you do indeed have relationships with other people that don’t involve him. That, or he’s embarrassed he got called out.

you’ll naturally come across NESS if you’ve already met kaiser and at first, you simply took him for the more timid type which could be the reason why he follows the former around like a lost puppy. wrong. not in the slightest.
well that’s a little harsh, but you mean that while he definitely has a bashful quality to him, he also seems to flip completely if you dare make a comment about kaiser. it’s a little scary. in spite of his dedication shall we call it, he’s actually one of the easiest mers to get along with. talk to him normally, avoid the topic of kaiser too often, spare some affection for him and he’s all over you soon enough!
just being generally nice around him is something he’ll appreciate it even if he doesn’t say it outright. poor thing is a little unfamiliar with people showing him basic human (or in this case merfolk) decency. makes you want to pat him on the head and spoil him a bit/squish him until he breaks — depending on what type of person you are, i guess.
when he gets more comfortable with you, ness is also clingy. like, really clingy. practically chasing after the other mers if they dare come within 10ft of you kind of clingy. it’s one of those rare moments where you appreciate the fact that kaiser is there since ness is still able to be reasoned if he’s there with him. sounds a little toxic at first but just set him straight and be patient with him. the end result is (hopefully) a slightly more relaxed version of him.
“…You alright, Ness?” you ask hesitantly. The merman in question is suspiciously quiet, especially after he just got into a mini spat with someone else.
Now, he looks up at you as if you’re a saint which weirds you out even more. He nods his head, before asking, “Are you worried about me?”
You’d think it was intended to be a snide comment, if it weren’t for the fact that you were dealing with Ness here. Besides, he says it so sincerely that you’d feel bad for poking fun at him. Maybe later though. “Of course.”
It seems to light up his whole world.
