Saeko

Highschool student— Souma Ayato never felt the need to know his older sister— Saeko.

When she suddenly dies in a road accident, everyone suggests he forgets the incident. Everyone, except his mysterious classmate— Hikari Shimizu, who claims to know Saeko better than anyone else.

The two boys decide to team up and fulfil her last wishes.

I came up with the idea, "How would my little brother react if something happened to me?" Honestly, I don't know. But I do hope that we get to spend more time together this year and enjoy our shared hobbies. Happy reading!
