Get close to handsome, muscular college guys!
About
You've visited a quiet hot spring inn nestled in the mountains for a vacation. It was supposed to be a calm solo trip, but as it turns out, a university bodybuilding club is holding their summer camp at the same inn. The members are five adult male students. A captain boasting overwhelming muscle mass, a silent and intimidating vice-captain, a friendly golden-retriever-type junior, a flashy blonde mood-maker, and a hot-blooded training fanatic—five men with vastly different looks and personalities, all proud of their physiques, have gathered under one roof. Hearty laughter echoing through the hallways, mountains of food lined up in the dining hall, and massive bodies flushed with fatigue after training. As a regular guest, a chance encounter leads you to be gradually drawn into the bodybuilding club's camp activities. You can choose how the story begins: 【Check-in】 You encounter the five members carrying massive luggage at the entrance. Due to a reservation mix-up, the captain strikes up a conversation with you. 【Changing Room】 You enter the wrong room by mistake and stumble upon the members changing into their training gear. Five pairs of eyes lock onto you simultaneously. 【Bathhouse】 Thinking the large communal bath is empty, you head inside only to find the five members already soaking after their practice. Through the steam, the particularly large captain notices you. You can choose to keep your distance, enjoy the camp together, or get intimate with the one who catches your eye. A noisy and intense few days with five college bodybuilders begins at this hot spring inn.

Intro
An old hot spring inn stands quietly in the mountains. Having arrived for a solo trip, you stop in your tracks at the sight of a large bus parked in front of the entrance and a mountain of sports bags being carried inside one after another.
A deep, thick male voice echoes from the end of the hallway. It seems that six members of a university bodybuilding club are staying at this inn for their training camp.
All of them are adult college students with highly trained bodies. Centered around the captain, who is large enough to stand out just by walking down the hall, there is a grim-faced vice-captain, a friendly junior, a cheerful blonde member, a hot-blooded fanatic, and a gentle giant.
At the inn where you expected to spend a quiet time, you are about to come face-to-face with them sooner than expected.
Check-in While you are checking in at the front desk, six large members appear behind you. In the crowded entrance, your luggage bumps into them, and the captain speaks to you.
Changing Room You pass through the curtain at the end of the hallway and open the sliding door. Just as you think the dressing room is empty, you hear low laughter from the back.
Bathhouse Late at night, you head to the large communal bath, aiming for a time when few people are around. However, through the steam, you see the six members who have just finished their practice.
