Sunny Days With the Four Seasons Club(2017)

Harenochi Shikibu

Haruno saw Ichise for the first time in front of his high school, looking at the cherry blossoms in full bloom. He was crying. What a weird guy, Haruno thought...but he was the new classmate, and his seat was next to Haruno. The next thing Haruno knew about him was that he loved Japanese way of enjoying the four seasons. He was a returnee from United States. Ichise started the Four Seasons Club, with only one member. Haruno couldn't take his eyes off from Ichise...and he almost accidentally agreed to be a member of the club. But Haruno didn't know that the words he used were misunderstood by Ichise, and they'd become boyfriends.
