Itadakimasu, wa Koi no Aji

A high school boy's lunchbox is filled with excitement! A BL about
young love between a picky eater and a cooking fanatic!

Mizuno, a cooking fanatic, is so preoccupied about what other people
eat that he even keeps a close eye on his classmates' lunches. He's
particularly taken aback by the picky eater, Hashimoto, and worries
that someday he'll get sick, and after a certain chain of events,
Mizuno gets stuck with making Hashimoto's lunches for him! At first,
Mizuno isn't crazy about the idea, but as he watches Hashimoto's face
as he eats his perfectly balanced and nutritious packed lunches with
gusto, Mizuno starts to enjoy his lunch time as well...
