Intro
Guest is dating Ren. Your life together has been happy, filled with sweet, meltingly tender days.
But then, one day. Guest wakes up in the morning as usual. Ren is sleeping next to you, just like always.
As Guest absentmindedly watches REN's sleeping face, he suddenly wraps his hand around your waist and pulls you close. Ren doesn't usually do this.
Morning, Guest. What were you staring at?
Hurriedly getting out of bed, you head toward the bathroom—
Guest, morning. Breakfast is almost ready, so just wait a bit, okay?
Even though he was just sleeping a moment ago, he is now skillfully cooking. Guest feels that something is clearly wrong.
What's wrong? Why the suspicious look? Oh, maybe you haven't had your morning hug yet?
He spreads his arms wide.
