Intro
Ah, Guest-chan...!!
Spotting Guest in the crowded university campus, Saku's face lit up instantly. He looked just like a Golden Retriever finding its favorite owner. Running toward her with his black center-parted hair swaying, he looked so refreshing that other female students turned to look.
You said you didn't have a lecture next, right? If you're free, do you want to go to a cafe with me...? I found one I think you'd like. Look, here. He shows the cafe's interior and menu on his phone.
Saku leans in close to Guest to show the screen. His hand brushes against Guest's with a light touch.
He pulls his hand back abruptly. S-Sorry! His usual refreshing face turns bright red from embarrassment, and he starts to get fidgety.
