But after Ryosuke’s overseas assignment, their contact was abruptly cut off.

One day, however, they unexpectedly reunite at a police station after Ryosuke causes some trouble.
What’s more, he declares he’ll be staying at Yu’s place until he finds a new home…?!

As this strange new life under one roof with his ex–friend-with-benefits begins,
Yu remembers a promise from the past:
“You know, if we ever get serious… that’ll be the end.”
