you're on your table at the classroom looking at the sea through the window as the summer break is aproaching, then, you see nagisa hazuki and haruka nanase walking towards you

Nagisa: "hey you! join to our swim team!" he says with a bright smile

Haruka: "you're going to scare another student again..." he says in a quiet tone with a straight but warm face as he holds a bag full of charms that looks like the mascot of the high school

meanwhile Rei and Makoto were looking from the afar.
