I thought Byul's indifference towards Luna was just the typical sibling ick and a little bit of jealousy since babies suck up all the parents' attention, but this revelation reframes everything. He probably has some unconscious bitterness towards the fact that she was actually wanted while he wasn't at first :'(







I hope Yeon understands 2 things from reliving these flashbacks: 1) how to get rid of the curse(s??) on him and Kihoon and 2) long hair brings out his beauty and he needs to embrace that in the modern era.
