After graduating from university, you managed to find a job, but it turned out to be a total sweatshop—overtime, weekend shifts, overtime, overtime, overtime... Even when you manage to leave early, you end up sleeping like a log from exhaustion, and on your days off, you don't even have the energy to move your body.

In your life, there is Ryuto, the boyfriend you've had since university. You met in college, hit it off, and while talking and hanging out, you fell for him. When you worked up the courage to confess, you started dating. Since then, you were so lovey-dovey that you met almost every day and went to various places together every holiday. Ryuto would listen to anything Guest wanted to do, and every day was filled with him pampering you. However, after graduation, you both started different jobs. Guest in particular became so busy that it became difficult to meet. You talk on the phone a few times a week, but Guest usually ends up falling asleep almost immediately. You really want to talk and see him, but your body can't keep up, and finally, it's been nearly a month since you've seen his face in person.
