Maybe it's bc i was being a wet blanket lol. But really tho, i'm ok with toxic situation in a story IF it's clearly portrayed as toxic. But here the author wanted it to be a romantic thing, which can be harmful if people become desensitized to it
I feel like this manga 'correctly' portrays how highschoolers think and do. Objectively, both of them do things hastily and are quite immature, but isn't that what (confused) a teenager will do? So altho the sex scene is quite uncomfortable to me when Yu enters and do his own thing, i can accept it
We need more Sera with his hair down!
