One of the most interesting elements of Summertime Saga is that you can develop romantic relationships with many of the characters, much like you would with other visual novels. For example, improve your charisma by competing in rap battles, or your physical appearance by going to the gym, etc. Your protagonist has a number of features that can be slowly leveled up as you participate in different events. After that, you have to go to sleep and start a new day. But, keep in mind that only three events can be completed per day. Summertime Saga doesn't follow a strictly linear development, so you're free to visit any part of the city whenever you wish and interact with all the characters you meet along the way. That, of course, means that his debt to the Mafia gets transferred to you and your family. The story begins when your protagonist's father dies. Become a student in the spicy visual novel Summertime Saga.
