Where the black hair dude at

I think he’s the one that’s going to be Jin’s actual love interest. The black haired guy at the beginning

I don't think so because Jin seems to be a magnet and have a history with blondes that have red eyes, and he's only ever called Tehir and Charin attractive, so more than anything I think the author is pretty much setting up the stage for Jin x Tehir. As well as Jin and Tehir seem to have a big feature in each other's past when they were in the daycare. Jin 'bullied' Tehir which fucked Tehir up, leaving him to hold strong feelings 'against' Jin until today and the only sunnyside daycare classmate Jin seem to have ever interacted with, in those days, was Tehir.
.
I mean I don't think its random that when Jin got separated from the other Sunnyside Daycare classmates, he went and fell in love with a blonde with red eyes who closely resembled his former blonde Sunnyside Daycare classmate: Tehir. I think it'll be very weird for the author to make Jin only ever call the Blondes with red eyes attractive and have Jin go on a whole rollercoaster ride with his emotions with one of those blondes to then make him end up with a black-hair dude where Jin never really had any positive opinions about, or even had a slight inclination of attraction towards.

That’s true I simply thought so because often the move is always to end up with the one “you hated from the beginning” . Either way I’m excited to see how the story unfolds.

Oh yeah that also usually happens, it's a very funny and cute dynamic that I find myself enjoying. It's like enemies to lovers. This story really has a lot to offer so I as well am excited for its progression.

Indeed and I hope the author continues this path because lately a lot of authors have been getting “creative” with their stories or simply just lose the entire plot. Which means the story looses its spark and it becomes meh

oh hell nawwww pls revive capo

(oops my first comment didn't work) So far I'm really impressed with the themes and characterization that I have faith in the author cooking up something worth while. Definitely want to see why the author plays on these themes and the intent of certain characterization on our different unique characters. Hehhehe I'm really keen!

I’m very invested on this as well. It’s a new take on a story
