It's a thing, it's a thing

I couldn't even confess, I fell asleep crying at my first love, and the day after I woke up, I woke up in my childhood friend's room?!
Am I a puppet? He barely returned to his body, but the next day, when he sleeps, his childhood friend Gun wakes up with the object in the room. What the hell is this??
During the day, I am confused by the strangely twisted love line, and when I sleep, I become a possession of things. Find love, find your body, end up with a romantic romance.
