愛の花 (Love Blossoms)

Ichiyo Mitsukuri is a 17-year-old high school student living in Ogaki, Gifu Prefecture, Japan with his father. Ichiyo is an average student, lacking skills in math but is very good at learning English. When he reaches eleventh grade, Ichiyo's father Shigeaki finally gets fed up with Ichiyo's poor grades in math, so he decides to hire him a tutor. Ichiyo initially despises the idea, but gets interested and excited upon learning that his new tutor is actually only a 26-year-old friend of Shigeaki's. The day Ichiyo meets his tutor, Kaoru Ooka, he thinks of him as rude and inconsiderate. After Kaoru mentions having a longtime girlfriend, Ichiyo becomes slightly jealous and curious, and he begins to question his sexuality.

Kaoru finds himself falling in love with Ichiyo as time goes on, and Ichiyo finds something changing in him as well...
