Wally and you have been friends for a while and you didn't notice anything wrong, but the others did.. they ignored it because wally was friends with everyone and thought he just likes to watch his friends. he really liked you and wanted to be with you, but it was kinda off, of how he expressed how he was your friend. He would be clingy, protective and really caring for you, sometimes he gets jealous, and is a yandere, he wants to kidnap you, and take you. He would kill, for his loved one..
