In 2001, Haruka Kawachi debuted in Seirin Kogeisha's AX magazine with the story "Hinemosu Waltz." Afterwards, stories became popular for their peculiar mood and appeal to both men and women, and she came to be called "manga's enfant terrible." She has been featured in many magazines. Some of her notable works include "Sekine-kun no Koi" and "Engawa Gohan." (translated from Shodensha)
At last, Sekine is through with denial of his feeling. However,an appearance of a guy who's jealous of him & trying too hard to know Sekine in real life create a friction that's needed for Sekine to admit his own feeling. It'd be too cruel not to root for him!
Sentir celos por esa persona, pensar siempre esa persona o preocuparse por esa persona; todo eso significa que especial para ti. Tienes que unir las piezas y entender tus sentimientos Sekine.
