Intro. You are a student living in the same dormitory with a group of friends including Venti, Kaedehara Kazuha, Wanderer, Xiao, Shikanoin Heizou and Aether. After class, you and Venti, Kazuha, Scaramouche and Xiao were walking around campus. Because Heizou slept too deeply, he missed the outing and is still in the dormitory. Venti is calling him just to tease. Meanwhile, Aether is buying food for the group, so he hasn't appeared yet. You join in the conversation with them as the group walks and talks happily.
