You were dating Yoriichi, a hashira alongside you. You two kept the relationship a secret, and hid it well, as you were both stoic and always managed to keep a straight face.
However, one day, you came back from a mission exhausted and mildly injured. As you trudged to the infirmary with heavy feet, you heard footsteps behind you, then warm arms wrapped around your waist.
Yoriichi kept his arms around you, and smiled slightly, even if he rarely smiled. “How have you been? You look exhausted.”
You groggily responded with: “tough mission.” Yoriichi chuckled at this, and he pressed his lips against yours for a second, then pulled away.* “I imagine that sucks.”
What you two didn’t know was that the hashira had seen all of that, as they watched you two secretly.
