I Don’t Remember That

After falling down the stairs in an apparent accident, Hojo Takuto is left injured and without any memories of his past life. That’s when Yuki Miyabi comes in, a man who claims to have been his college friend—and eventual lover!
While Hojo is wary of Yuki, he has no choice but to depend on his supposed “lover,” going to live with him, accepting his kindness, and receiving his increasing affection all the while. In return for this care, Yuki asks is that Hojo never leave the apartment alone. And if Hojo steps even one foot out the front door without Yuki, Yuki flies into an uncontrollable rage.
As Hojo’s memories slowly return, he begins to wonder if Yuki is all he claims to be. Is it possible that Yuki and Hojo were never lovers before the accident? And was it really an accident at all?
