I think its Taekwang, because after seeing police report on So In's death, he is coming to the school to confirm something, of course he takes the keys with him.
hope they have a clear and logical explanation about Eun Byul..
I just want Eun bi to end up with Tae Gwang... Nothing else matters to me... Even if they say Han Yi An actually a girl who's been acting as boy , I dont mind....Let it be...
If it is upsets you in any way, then I am sorry...
