When You Wake Up Tomorrow(2018)

Ashita, Okitara Kimi wa

Hironori and Kento have been live-in boyfriends for three months. One average morning, as Hironori was enjoying a cup of coffee, Kento asked a question, "Can I fuck you during your sleep when you look like you're in good shape?" ー much to Hironori's surprise. While Kento ended up waving it off, Hironori was plagued with the thought for the rest of the day. Hironori then reminiscences over the day he met Kento and the events that led them to their current relationship. One thing is sure, as long as it's with each other, anything and everything is enough.
