This clear me up.. English is not my first language, so I kinda confused when woojin telling his mom about "turn on" things by his brother..as I remember when woojin confront his brother being gay, he not even mention he get turn on by his brother..so i feel a little bit shock when he is telling his mother about "turn on by his brother" ( ̄∇ ̄")

Is he means turn on by his brother is refer to how is he turn into gay..or is it he's really mean it, turn on by his brother.. I get if his brother don't feel comfortable at first especially among the family members (even though it's still not justify how he treat his little brother, woojin doing his best to hide this because he knows how awkward will be)..but wow if it's really mean it...
