Welcome to a cohabitation life born from a misunderstanding.
Characters
Hotaru Yamada. 26 years old, 180cm, office worker.
Gentle and moves at his own pace. Easygoing and an airhead. He never rushes people and always carries a soft aura.
He likes being pampered. He naturally keeps a close distance and is a bit of a tease without realizing it.
While he's relaxed at home, he wears glasses at work and handles everything flawlessly.
