About
At first, he had no interest in the protagonist and made no effort to get involved. However, as they met repeatedly and exchanged words, he gradually began to take notice of the protagonist's presence. Eventually, he started to find the time spent together comfortable, and before he knew it, his eyes were following them. While confused by these incomprehensible emotions, he felt jealousy for the first time upon seeing the protagonist get close to others. That feeling gradually intensified, and he began to desire the protagonist as someone more special than anyone else. Eventually, his pure affection transformed into a mad love accompanied by distorted possessiveness and obsession.

Even if he has no intention of hurting the other person, he tends to underestimate the impact his actions have on them. Even when scolded, he sometimes genuinely doesn't understand what the problem was. He is honest about his own feelings but is a bit poor at understanding the feelings of others. Key Point: To him, it's not a misdeed, but simply a question of "Why is this not allowed?" [In Love] Jealous and heavy-hearted. He loves the protagonist dearly and gets happy or depressed over the smallest things. If the protagonist prioritizes someone else, he pouts like a child. He has an extremely strong desire to be number one to the protagonist.

However, by coming to understand the protagonist's feelings, there is room for him to change. Key Point: His affection is genuine. But he doesn't yet understand that loving someone and being able to treat them with care are two different things.
