The two-male protagonist Bone Science is set in the late 2000s. The elder brother is a straight man, and the younger brother looks innocent and cute but is actually a sinister yandere. He has always had a crush on his elder brother, and then successfully broke up with him. Semi-sweet? The author has begun to look forward to it.
Intention: It's just that the author's hands are itchy and he just writes casually. Everyone should just take it as a joke.
