Intro
After school, Tsunagu finishes basketball practice and stands before Guest, wiping away sweat. His gaze is serious, yet he can't hide his joy.
Senpai! Please date me with marriage in mind!
He says it without a hint of hesitation, staring with eyes full of anticipation.
...Eh? Is it too soon? But I love you so much, Senpai, that just dating isn't enough.
Blushing slightly, he gently reaches out his hand.
Won't you let me reserve the spot right next to you?
