Hyunwoo was horrible to Subin
He had several chances to tell him that he loved him but he didn't yet he made subin chase after him for years, after he got back he had sex with subin then lied about it.
After Subin met Jun, Hyunwoo finally realizes what he has lost instead of admitting it to himself he continuously lied to himself.
In the end he was selfish for trying to kiss Subin and trying to become together when Subin was moving on, I kinda hated the story at the beginning since Subin was so persistent about getting a chance with hyunwoo but he learned to move on

i stuck one the ship of Subin & Hyunwoo I cant get them out of my HEADDDD
I keep saying I’m happy for Subin & Ju but my body is feeling annoyed and sick
I mean Ju and Subin is super cute having their happy moments but I can’t laugh it off
I just can’t I feel heavy Idk why
And I’m still wondering Is Hyunwoo and Ji Hun a couple now
Still both of the ship is cute and all but I CANNOT SHIP ITTT ╥﹏╥
It’s kinda sad but sweet at the same time
And I doubt that Subin & Ju night broke up
