Kae, who can’t seem to be as honest as she’d like to be, and Hiroto, self-conscious about his (lack of) height and childish appearance, are known for bickering all the time. Kae has kept her crush secret from Hiroto, but when he returns from summer vacation a tall and handsome flower boy… will she finally be honest about how she feels?

From Chibi Manga: A story about an energetic girl and tendency boy!

From Dazzling Scans:

Natsuki, an otaku high-school girl who'd rather spend her money on manga than pretty dresses, accidentally injures a creepy-looking mangaka named Kiritani Taichi. To repay him, she agrees to be his character model until he fully heals. Kiritani turns out to be a popular shoujo mangaka under the name Ichijou Kiriko, who is also Natsuki’s favorite author! Plus, underneath that disheveled hair Kiritani is actually a good-looking man! What will become of these two?
