Welcome to Tropical Island. "But onii-chan, you're just some part-time bum, aren't you? On top of that, your age equals the years you've never had a girlfriend, right?" The player (that's you!) is a part-timer who lives an uneventful, boring life. One day, you win the prize draw at the shopping district. The prize: a trip to an island in the south -- you decide to take a 30-day vacation. "I... want to make this a nice vacation...! I want to change myself in this trip!" You decide to grow out of your dull, boring life and get a girlfriend. "To get a girlfriend, you have to first get close with a girl! If you don't create a bond with one, then nothing will ever happen!" On your vacation, you meet all sorts of girls, each of whom has something troubling them. You can talk with them, share a drink with them, and go on a date with them. "Let's make this a nice vacation." In this vacation, will you finally come out of your shell, and manage to make a girlfriend?
