As you move along in the game there will be missions that you have to do something for a certain girl in order for her to like you. You cannot just go up to any girl. Also, even there is a girl that likes you, you can not make out with her right away. You need to give her chocaletes and flowers. You can buy those things at yum yum market wooch is in town. You unlock the town after you beat chapter 1. You give them gifts so they will kiss you, or if you have the upgraded kissing after beating ther 5th art class where you can kiss without gifts. This will make them like you if you do that a lot. Also, if you do missions for them they will kiss you. You know they like you if it says it on the screen after a mission you did for them or, if you kiss one of the cheerleaders they will put their leg on you while you are kissing and kiss you for about ten seconds if they like you.
