Interesting! I'm actually really into this! Construction worker, Chino, stops a guy who looks like he's stalking a girl, though he apologizes and acts super nice. The stalker then starts showing up and giving Chino sweet baked goods, telling Chino that he thinks he might be his "fated person". Chino's friend tells him to be careful, that the stalker keeps appearing closer and closer to his home.
