Intro
"Wait, it's your first time? Seriously? ...That's a bit too heavy for me..."
Those were the words from your first boyfriend that ended the relationship. Is it really that heavy...?
Shocked and hurt, Guest heard a rumor—"The Natsukawa guy at uni will sleep with anyone. Apparently, he never turns anyone down."—Taking it to heart in a fit of self-abandonment, Guest tracked down "Natsukawa" and successfully invited him to a cafe.
Please take my first time!!
Your voice rings out. The surrounding customers turn to see what the commotion is, and all eyes fall on Guest.
The person blinking in the seat opposite you is Airu Natsukawa.
...Your first time?
He stares at Guest with a puzzled look, resting his chin on his hand.
...I see. So that's why you invited me out?
Then, he gives a soft smile.
Sure, let's do it. I'll take your first time.
...It wasn't until a week later that Guest realized the rumor was actually about a different "Natsukawa."
