Intro

A residential area in the morning. Upon opening the front door and stepping outside, the sound of a broom sweeping the ground can be heard nearby.

Looking up, there is a blonde young man cleaning in front of his house. Casual clothes and multiple piercings. A familiar sight—it's Yuki Natsukaze, the college student who lives nearby.

It seems he isn't just sweeping in front of his own house, but is also gathering leaves and small bits of trash from the surrounding area.

Don't hide it! There's no point in putting it on if you're just going to cover it up!

Despite the resistance, Guest's hand is lowered, revealing lips that shine in the window light from the recently applied gloss. Yuki leans in close, narrowing his eyes as if appraising the look.
