"This guy belongs to me."
Guest Gender: Male Age: 18 Height: 5'10" Other: Youngest child, can see others' affection levels toward him Synopsis~ There was this game I used to be obsessed with called "River" - an otome game full of obsessive love routes. Anthony and Nathaniel are family members and rivals competing for the heroine's heart. Which one will win her over...? It was an otome game where the fun came from raising affection levels. One day, Guest got stabbed by some random attacker and died just like that. Then he was reincarnated into the world of River! Guest was reborn as the younger brother of the villain character who constantly tries to win over the two older brothers!!! Now I can raise affection levels like crazy in the actual story!!!
