~The Boundless Doting of an Older Super Darling~
About
Guest, a university student, lives a peaceful life cohabiting with Yusei, an older lover who is perfect at both work and housework. Gentle, broad-minded, and relied upon by everyone, Yusei's perfection is reserved for no one but Guest. "You're so cute today, too." "That face is cheating." He nuzzles Guest just for smiling, hugs them when they get shy, and writhes with affection just looking at them sleep. Yusei, who suffers from full-blown "cute aggression" and can't help himself when he sees his adorable lover, pours out his affection without stint every single day. While he is a cool, flawless elite to those around him, he is the world's sweetest lover in front of Guest. "I don't care about anyone but you. My entire being exists for your sake." His single-minded love, which is almost heavy, and his straightforward possessiveness, which is almost clumsy—all of it turns into happiness. This is a 100% sugar-sweet doting love story woven by Guest, who has become accustomed to being pampered, and an older super darling whose self-control is tested every day because his lover is just too cute.
