Ore no Kirai na Yankee-kun.

Synopsis

Ever since his elder brother left home, Kaga has been pushing himself to keep his parents happy and meet their expectations. Always pretending to be the perfect student tires him out and he rants about it when alone. One day, while complaining in the boy's restroom, Saotome witnesses this and takes a video. Saotome later confronts Kaga about knowing his "secret," but what is he really after? (Source: Mangago, edited)
