The friend is actually chill lol. I had my suspicion at first too and thought he's 2nd ml but he's not, he's just the overprotective friend. Altho it does feel like there's some hints dropped about his feelings towards hajin but it's not romantically at least? He actually likes both top and bottom, he let ml get close with mc cuz he knew ml is a nice guy. He's actually even quite supportive for their relationship lol. At the very least he's obsessive but not possessive towards hajin and dude did not do any red flag things and have only been protecting hajin as far as I remember.

He said that those two suits each other very much (not in a jealous tone but in a cheerful happy way) . I actually like that dude lol bro's just chill even if he got obsessive tendencies he never cross any lines. It was never confirmed if he actually do have romantic feeling towards hajin or not though. He's just happy to see hajin have someone he can lean on since his family is trash

Dw cuz I also read the novel before just to see if he actually the 2nd interest or will do something to mc too lmao. He never want to date him or took a chance with mc even when the mc and ml did not meet each other for a year in the side story. There is 2nd interest but it's not the bff, it's the og novel male lead
To those who read the novel can you please spoil me about the friend. He is kinda sus (even tho hi is so damm hot)
