MANGA: Hidamari Starlight

Hidamari Starlight – Ichikawa Ichi

Aoi Yoneda has been taking care of his step-brother for ten years, ever since their parents died in an accident. Haruto loves his big brother, however, he made a promise to himself to stay by Ao-kun’s side as a brother until his 18th birthday. But then after? Only time will tell what happens between these two step-siblings.

I love brother complex but this was kinda boring and short on fluff.
