Explanation of the Characters’ Height

We figured Makoto’s approximate height from Haneta Blog’s average height for girls according to age. She stands at approximately 5 feet and 2 inches.

For Kousuke’s height, we based it on Haneta Blog for their average height for boys according to age. He has an approximate height of 5 feet and 7 inches.

Since a photo on Pinterest by Mayline shows Chiaki and Kousuke are almost the same height, we concluded that Chiaki is a few inches taller than Kousuke.

This means that Chiaki is approximately 5 feet and 9 inches, considering he’s slightly crouching down on the photo.

Explanation of the Characters’ Age

Makoto’s age is mentioned on the plot found in Anime News Network, she is 17 years old.

Additionally, Makoto, Chiaki, and Kousuke attend the same level of education, senior high school, so we concluded that they all have the same age – 17 years old.

It is also usually the age of Upper Secondary School students in Japan according to K12 Academics.
