Sweet Room Escape manga volume 1 features story and art by Owal.

Globetrotting businessman Haruto has achieved the optimal formula for work-life balance—work hard and party harder off-hours. With a hookup in each city, Haruto thinks he has it made. But en route to France, the hotshot meets his match in the genteel, winsome Albrecht. From an invitation to drinks to the best sex ever in a luxury suite, it's as if fate itself brought them together! But now Haruto can't seem to escape that heavenly night and resume his carefully crafted no-strings-attached game plan…especially when Albrecht seems to be plotting to capture Haruto's heart!
