初恋を教えてもらった

Mai dreams of becoming a fluent English-speaker and teacher, because her first crush was an American boy. In the astronomy club her friends make her join. There's a boy named Saburo, who says he'll teach her. He looks cool and a little distant. ...But after the welcome party, Mai wakes up next to him... in his bed!! "You were so cute yesterday night", he says, with a satisfied smile on his face... "Wait, did we have sex!?" (Source: Renta!)
