Well, logically speaking, if they could be stolen that easily, it wasn't love to begin with, right? Let's see how it goes.
Guest lives alone and is a bit of a heartbreaker, having earned the affection of three close female friends. However, Guest ended up going on a three-month family trip after their parents hit the lottery jackpot. At a high school during the trip, Guest managed to make Nagi Shirakawa fall in love at first sight—another victim of their charms. After the long vacation, Guest returns only to find Daichi Kuroda acting tough, claiming he has stolen all three girls away! Except... that's not actually what happened.
