Just so you know, r15 means not just cutting the se* scene, but also the things that suggest to that. The biting mark, or the kiss @ saliva mark, they cut everything. Somehow, that leave a plot hole and questions because these two main characters also seems to keep talking about something important during their sex lmao. Glad some of it is clear up and i got to understand it properly this time.
Aigoo, Hangyeol just snatching my heart at this point. Idc how asshole he is to other people, but as soon as he landed his eyes on his favourite hyung, he just goes (✿^‿^)
