Synopsis
One morning, you wake up with no memory. “Where am I?” “Wait…” “Who am I?” The protagonist (Usomiya Masashi) has completely lost his memory!
While exploring an unfamiliar house with no recollection of his own name, he discovers the following: he apparently has three younger sisters, they all live in this house together, and their parents are currently away on an overseas trip.
For someone with amnesia, this means suddenly living under the same roof with complete strangers—high school girls who treat him like a brother. Just how much longer can his self-control hold out…?
Will his memory ever fully recover?
