Tsutomu Shimbashi

He is small in stature and has an ordinary appearance.

Until junior high, Tsutomu wore glasses and had a notably plain presence.

When entering high school, he dyed his hair and switched to contact lenses, making his "high school debut."

At the beginning of the story, he was slightly chubby, but after catching a cold during his first summer in high school, he lost weight and settled into an average build.

Tsutomu has a crush on Sumire Uguisudani and spares no effort in trying to become more popular.

However, he tends to have low self-esteem at his core, which often leads to his plans backfiring.

He feels a sense of kinship with Hana Tabata, who has a similar personality, and often ropes her into his schemes or asks for her advice, possibly because he feels comfortable around her.

As a result, he unintentionally sparks jealousy in Yosuke Ueno, though he remains oblivious to it.

Tsutomu proudly refers to himself as a "Love Master," but in reality, he has zero experience in romance and frequently digs himself into awkward situations.

That said, he does have a keen sense of observation and was quick to notice Yosuke Ueno’s feelings for Hana Tabata.

Even though his advice usually comes from magazines or secondhand information, he is sometimes able to offer remarkably keen insights.

One of Tsutomu's secret hobbies is singing alone at karaoke.

He is an outstanding singer, surprising anyone who listens.
