Ikuto wants Amu to go home together after class, but the teacher wants to talk to her after class, so who Amu will choose, Ikuto or teacher? In the class you have to kiss Amu non-stop to increase her feelings for you. When the teacher turns away, you can start (click left button without releasing), but be careful, the teacher might turn back at anytime. When you sense that, release the left button, and then you’ll be safe.
