Kimochiii Jugyou Shiyou
Man, Hina's the most annoying FL I've encountered in a while. She was selfish, pushy, self-centered, irrational, while also not having a back bone. It was a miracle Aokii put up with her like that. Aokii obviously had his flaws too, not being open and honest about his feelings. It was pretty obvious that Hina was insecure. He didn't need to buckle to her every demand, but he could've done a bit more to reassure her. The other characters were either one-dimensional or annoying or both. Especially her two friends. They seemed to have no personality whatsoever, aside from being Hina's trusty friends and love-assistants. It was lazy character writing. All in all: This manga was a waste of time to read.
