I haven't finished watching episode 8 but these are my final conclusions when it comes to who Do Ha should be with. I think he should be by himself. He didn't have much chemistry with any of the characters and if we are actually looking into their personalities/actions I would prefer to have him end up with the team manager. My reasoning? He was the most mature and the greenest flag. I know a lot of people would prefer between him or thebest friend, but if we are watching the series through a real life lenses, the best friend was kind of obsessive and violent and overall a red flag. Besides the unconsensual kiss while Do Ha was drunk, there's also no justification for him to punch Haram just because he took Do Ha to the beach and he lost is phone. Also he showed a bunch of times signs of jealousy and immaturity in his reactions to Do Ha's interactions with the other two. Overall I'm dissapointed with the series, which had potential to be better.
Am I the only who only is NOT team best friend and the reasoning lies on the non consentual kiss when Do Ha was clearly under the influence. And I know someone will say team leader also hugged him without asking, but at least he apologized for doing so. I kinda regret starting to watch it while it was airing as i genuinly wouldn't finish it if he ends up with his friend. Not only the kissi situation but they just give me bro/friend vibes so I don't really see a romantic spark there. As for Haram, I don't really see any chemistry between him and the ML but I think it's also Do Ha's character fault as even with the other two there doesn' seem to be any interest from his POV. I think by this point, Do Ha's feelings should have been more noticeble, not him just randomly confessing in the last two episodes to one of them. For this reasoning, I do think he will end up with his best friend because its at least the relationship with the more substance.
