[Honestly, Izumi likewise can't say that he has much experience with typical summer fun, though his reasons are different from Tsukasa's. He can't swim and wilts in the heat, so even though he usually goes to the beach with his family at least once every summer, he's never the type to jump forward and suggest doing all types of summer activities (unless laying on the floor at home in the AC counts). Sparklers are definitely very summery, though, and something they can do at some point!]

It's okay. Tonight's just for stargazing, anyway. [Isn't that right?] Besides, if Leonii gets mad at you, then I'm to blame too. We're partners in not-actually-crime. ....Did you want to sit down somewhere to watch the stars, or just walk around?
