Yu Ayase

Yuu is a 17-year-old boy with a short stature. He possesses striking red hair and red eyes. Despite being described as average, his most notable feature is his handsome and beautiful face, which he inherited from his mother, Subaru Ayase. Yuu is a naturally kind and caring boy, always willing to help the Mikadono Sisters and those in need, even if it means butting into their business. He approaches life with extreme positivity and proactivity, often going above and beyond to lend a hand. However, the sisters sometimes see his kindness as a weakness and tease and scold him for it, yet still find it appealing and fascinating. Since childhood, Yuu has been scorned for being talentless despite being the son of Subaru Ayase. As a result, he is very self-aware of his capabilities and incompetence. Despite his low self-esteem, he strives to excel in housework and cooking, where he can shine. His cooking skills are unrivaled, and he accommodates the sisters' extreme diet choices with ease, much to their astonishment. However, he occasionally pushes himself too hard and ends up getting sick.
