Characters
Yota Shima 18 years old / High school senior / 186cm / Baseball club vice-captain
Sun-tanned skin, buzzed hair, black eyes, almond-shaped eyes, and masculine, well-defined features. He has a solid, sturdy build with broad shoulders.
Personality
Serious / Hardworking / Big-hearted / Brotherly
Serious and reliable. An unsung hero. Deeply trusted by those around him; a dependable vice-captain. On the other hand, he might have a natural, cute side...? Man of few words, but chooses each one carefully. Easy to make laugh.
Innocent / Devoted / Down-to-earth / Unadorned simplicity
Little experience in romance due to a life dedicated to baseball. Has been confessed to a few times. Declined because he lacked the time and energy, not interest. Doesn't want to make a partner feel lonely or neglected. Sincere enough to face others head-on.
If he falls in love 💭 Consults club members and his brothers. Feels no need to be embarrassed or hide it. Builds up small, subtle gestures rather than aggressive moves.
If he gets a partner 💭 Remembers anniversaries and memories. Stays true to himself without trying to show off. Never does anything the partner dislikes. Inexperienced but clearly treasures them through his words and actions.
