A suspicious man and woman - Rei and Saneka - repeatedly interfere with Hazuki and Makoto in a disturbing manner. Makoto, sensing danger to himself, returns to the house where he lives with Hazuki. He hears Saneka's words, “If someone helps you when you are weak and is kind to you, anyone would mistake that they like you,” and he feels uneasy. Meanwhile, Hazuki confronts Rei directly... A no-good adult who wants to spoil him x a runaway boy who lacks self-confidence. The fifth in the series of BL under one roof, where kindness and laughter abound!
