Kawaiku Naitemo Nigashite Agenai

Aoba is a first year high school student who is really close with his older brother's best friend, Shima. After he entered the same high school, he has been having lunch and going back home together with them, especially with Shima. But he finds himself feeling unsettled when Shima sometimes looks at him with a burning gaze that seems as if it's coiling around him! (Source: Gentosha, translated)
