飯塚先輩×ブレザー -姉キュン! より- THE ANIMATION

Iizuka is chairman of Baseball club and one year older than Toyomoto. Iizuka-senpai and Toyomoto-kun always go to school together because Iizuka's house headed to school past Toyomoto-kun's home. Waking up Toyomoto-kun every morning and getting him to the morning practice baseball club has become his habit. Until Iizuka finally had a passion for Toyomoto-kun and conveyed his feelings at the time of graduation. Since Toyomoto-kun also wants to go to the same high school as Iizuka, he has to study harder to get into school with Lizuka. With that they made an appointment for dating after Toyomoto-kun finished the test. (Source: Nekopoi and Has Been Translated)
