Main Focus:




Kotaro is an average height young man with brown eyes and brown hair. His haircut is short and kept close to his face, prominently showing his forehead. In his second year of high school, he gets a little taller, his hair is noticeably longer, and gives him longer bangs but still shows off his forehead.
Both in middle school and high school, Kotaro keeps his uniform top open. He wears a school-issued white shirt with an orange undershirt underneath, which can only be seen from the top.


Hina SetoguchiEdit

Childhood friend he's been in love with for years. He's always found himself taking care of her or trying to make her happy, which becomes his mission statement later on in life. 

Koyuki AyaseEdit

Upperclassman. Kotaro is jealous of him because Hina likes the latter boy, but doesn't directly come after him.

He does get to question him for making Hina cry after she was rejected, but Koyuki only advises Kotaro to look after his own love and go after Hina before he regrets it.

In Kore Seishun Understand, he and Koyuki do some gardening together, showing that they're not on bad terms with each other.

Arisa TakamizawaEdit

Classmate and friend since middle school. Kotarou helped her deal with her bullying by cleaning off her written-on desk, and the two have been friends ever since. Arisa likes to tease him about his crush on Hina and tries to push the two together.

Ken ShibasakiEdit

Friend since at least middle school. Likes to tease Kotarou about Hina, and Kotarou often has to keep the boy in line.

Kodai YamamotoEdit

Friend since at least middle school. Yamamoto talks to Kotarou about his various problems and reassures him or gives him advice when needed.

Natsuki EnomotoEdit

Older sister. They bicker and fight often, but still like to support each other.

Yuu SetoguchiEdit

Neighbor and childhood friend.
