Team Taku: (I'll try to keep it simple :>)
- Taku is able to see when Haesoo is uncomfortable and immediately comforts him
- Imo they have great chemistry, they're both artistic and are interested in each others career
- Haesoo opened up and reached out for Taku. not for sex, for emotional support (i'm talking about the chapter where Taku put a band aid on Haesoo's finger).
- Speaking of band aid,, I loved that scene. It looked so symbolic, as if Taku is Haesoo's healing.
- BRO THEY JUST CUTE AF TOGETHER, THE WAY THEY HOLD HANDS N SHIT
- In some chapters Taku has been seen with a red string (ex. Chapter 37) which symbolizes soulmates in Japan.
- Taku said that Haesoo needs a change, and I believe that change should be Taku himself ;) (talking about their first car scene)
- Haesoo is the only person who's face Taku can clearly recognize bc this guy has a weird condition that makes it hard for him to memorize faces lmao destiny, just sayin.
- There are probably more but i'd have to check my notes and i'm too tired rn
These would be my reasons to ship them, because that's what you asked for. HOWEVER, I don't think Taku is end game (sadly) and tbh I think Haesoo should stay single but thats not happening.

I love Joowon but I don’t want him to be with Haesoo. I want him to find someone he actually vibes with, someone who can whole heartedly love him back. He deserves a better love! Not that Haesoo isn’t good but their chemistry together is off, he’s been chasing after Haesoo since high school and the love is one sided! Haesoo can have Taku, they can have their happy ending. Let the author give Joonwon someone who can finally give him the love he deserves! I hope we get a spin-off for Joowon after this story ends! He meets a super adorable Uke at a cafe or something ヾ(☆▽☆)

I've team neither cause everyone is using each; Haesoon is using Joowon and Taekyung and they're both using Haesoon. I feel all of them are very toxic and don't need to be together. Taekyung said he wants to see Haesoon hurt and wants to be with him only to toss him away. Joowon only wants Haesoon cause he doesn't want someone else to take his toy way; I feel like he only developed feels cause Haesoon's are slowly going away. Haesoon basically doesn't wanna be alone and will cling to anyone to make himself feel whole; he does care about if he'll hurt either of them but at the same time he also doesn't.
It would suck if Haesoon and Joowon become enemies but they definitely cannot become friends/family cause they've already crossed a line; you can't just forget want happened with someone especially when you've had sex...they've had a lot of drama happened between caused by both parties that just can't be erased.

For sure, even as factional characters they need happiness too! Especially since people reading this could also be going through this situation or have the same emotions they feel. I've stated in another post I'm more similar and have the same outlook on things like Taekyung and that makes me feel more involved and understanding to the character and makes me kinda happy to understand the story better. (yes, I feel like I can even be toxic like Taekyung too)
Can someone tell me why they want haesoo to end up with jowoon or with taku? Like why are you team jowoon/taku?
