@Han I think Siwoo will have more difficulty telling Suha than accepting Do-hyeok's love... who knows, if Do-hyeok asks Suha and his partner (I forgot his name) for forgiveness, it will be easier
@Luna actually that makes a lot of sense on second thought the fact that siwoo is even having s** with suhas toxic ex bf is betraying his loyalty in the first plac (not that i really think that matters tbh but i might just be a bad person)
