Team Suho.
Everything I write will be with respect to the drama.
So, Suho is the one who was actually attracted to her PERSONALITY and started liking her, even if she was bare faced ( yes that’s how it should be!) His liking for jugyeong is really -really genuine. He even thinks she’s pretty without makeup . And it’s also very clear after 6eps that she is actually very comfortable with Suho and she can always be herself with him.
As for seojun rn, I am sure he is not a type of guy who would care petty things like looks or jugyeong’ bare face BUT he started to pay attention to her only because he wanted something to get back on suho coz it seems to him as if Suho is having a merry time even after his friend’s death. Ik things and feelings will get real for him during the process but just the start of how he wanted her just to take revenge on suho doesn’t seem right to me.
Anyways I’ll patiently wait for the end and will support any one who jugyeong actually likes.
