Soren/Ryuu.

Before the tutoring sessions, Soren and Ryuu barely knew each other. They had attended the same school for several years and had seen each other drawing during breaks or after school on more than one occasion. Both were intrigued by each other's talent and, for a moment, considered approaching them to talk about drawing. However, neither made the first move. Soren was too shy to initiate a conversation, while Ryuu, although more extroverted, always ended up returning to his group of friends. Over time, they both grew accustomed to observing each other from a distance, exchanging only occasional glances before each going their separate ways, never imagining that one day they would end up spending hours together in the library.

Ryuu is 15 years old and attends school. He is 1.60 meters tall, making him shorter than Soren. He has reddish-brown hair with some black streaks, giving him a distinctive style. His eyes are a dark shade that complements his appearance, reflecting his expressive and energetic personality.

Soren is 15 years old and attends school. He is 1.64 meters tall, making him slightly taller than Ryuu. He has medium-length, very dark blue hair and fairly long bangs that mostly cover his eyes. He also has heterochromia: one of his eyes is dark pink and the other is completely white, a feature that gives him a unique and striking appearance.

Soren is a shy and introverted boy, so he finds it difficult to connect with people he doesn't know. However, once he gains confidence, he likes the nickname Sushi, given to him by his friends, though he doesn't show it. He becomes friendly and demonstrates his affection through his actions, as he finds it difficult to express his feelings with words and is quite quiet. He is sensitive and can be affected by other people's comments. He is also often nervous and embarrassed to show affection directly. In his free time, he enjoys drawing and skating, activities that allow him to express his creativity and relax.

Ryuu is an extroverted, energetic, and very expressive boy with a great sense of humor. He likes to joke around and is quite sarcastic, and although he can sometimes act impulsively, he always tries to maintain a cheerful atmosphere. He also has a nickname given to him by his friends, Yapingacho; he feigns anger when they call him that, but he actually likes it. He plays volleyball as a libero, enjoys BL (Boys' Love), knows how to cook, and draws occasionally, though not as much as Soren. Despite his positive personality...
