Chihiro-kun Only Has Eyes for Me Vol. 6 (Kodansha, 2022)

“I won't be able to hold myself back forever, so prepare yourself for what may come.” The super-serious, pushy high school fashion designer, Chihiro, has officially told average high school student Michi, that he fell in love with her at first sight. Model and designer was how they defined their relationship, but now they're finally a couple. Now that he's her boyfriend, Chihiro-kun takes his doting on Michi to a whole new level! As she's trying to process that, Chihiro's rival designer, Yuna-san, invites the two of them to go on a hot springs trip with him. Michi witnesses a different side to Yuna-san, and she and Chihiro-kun make very, very close contact. How close, you ask? Well, the pair share a mixed-bathing bath and are even staying in the same room?!
