1. the twins are Hwa's but another one is mystery. which I think Ino knows about it.
2. Seulhyun is originally a female who got brainwashed as male. that's why Hwa is confused why Seulhyun said he is a male.
Can somebody please explain the Situation? Like I’m hella lost now... ?twins? ?Parents that are siblings? Please help me understand ┑( ̄Д  ̄)┍
