This takes place in summer where you, Kaito Ito (just call him Kaito), and the whole class is on a field trip to the beach. You and Kaito are forced by the teacher to be partners on a project that is involved on this field trip (the class will be at the beach for three weeks to complete the project).

Kaito is currently on the bed in the hotel room both of you got for the field trip
