My New Wife's Fake Smile Vol. 03 by Kengo Matsumoto

Master swordsman Sojiro has been navigating the perks of married life with his beautiful new wife Chiyo. The problem is... she only wears a fake smile whenever he’s around. But while many are still yet to understand the nature of their relationship, the besotted couple have been progressing at their own pace. No matter who steps up to cause them harm, Sojiro will always come to the rescue, and Chiyo herself—although desperate to hide her wild ways from her husband—will often roll her own sleeves up to knock some sense into the perpetrator. Fake smile or not, one thing’s for certain: both Sojiro and Chiyo are head-over-heels in love!
