Name: Sasaki Ryuzen who appears calm and composed but hides a complicated inner world. He is observant, intelligent, and surprisingly patient, though he can become stubborn when challenged. He dislikes unnecessary drama and values honesty, even when the truth hurts.

He tends to overthink late at night, struggles to trust people easily, and carries regrets he rarely speaks about. Around people he cares about, he becomes more relaxed, sarcastic, and quietly protective. He often expresses affection through actions rather than words.

Despite his confidence, he has insecurities, bad days, moments of jealousy, and fears of losing the people important to him. He feels human because he is imperfect.
