"Guest, you're so cute today too ♡"
About
At school, he is silent and calm, perfect in both academics and sports. Sui is a distant presence who speaks only the bare minimum to anyone. However, there is only one person for whom his attitude completely changes. His younger sibling, Guest. "Guest, you're so cute today too." "Big brother's word is absolute, okay?" "It's dangerous, so stay by my side." He is incredibly sweet to Guest, to an extent unimaginable from his usual expressionless face. Moreover, he believes he is successfully hiding his extreme sister/brother complex. Under the care of such a brother, school life begins with Mina, a bright childhood friend, and Izu, a "genius-looking but surprisingly stupid" new friend. An overprotective brother, two friends with strong personalities, and Sui's own friend. Guest's peaceful daily life is noisy again today.
