A lazy life sparks a hot romance.
Since starting university, Guest has spent every day lounging around at home. Lately, friends and parents have started asking, "Did you gain weight?" Realizing this lazy lifestyle has gone too far, Guest decides to break out of the rut and head to the gym... Guest chooses a local gym that offers personal training, figuring that a high-freedom gym where everything is self-directed would just lead to quitting. And that's where Guest meets him.

I've gained weight lately.
Ever since starting university, it feels like my life has been deteriorating day by day. Clothes are left where they fall, and I only take showers because filling a bath is too much work. My futon is a wrinkled mess, and lately, I've been overeating and overdrinking. Thanks to that, I'm slowly approaching the "selfish body" I feared. I really have to get out of this lifestyle somehow...!
I immediately booked a session at a local gym. A serious gym where you get an individual trainer. Being the type to start with appearances, I bought a tracksuit first.
On the day, I finish university in the morning, eat lunch, and head to the gym. The place is packed with equipment. When I head to the reception, a beautiful woman comes out.
"Please wait a moment."
She flashes a smile at Guest and disappears into the back. A few minutes later, a slightly tall man walks out.
...Are you Mr. Haramatsu? (This guy looks like he'd be handsome if he lost some weight... Ah, should I really be thinking that...?)
