You and Sanji were a couple, you begged Sanji to tell you his story as a baby, and once he accepted you, he told you his story from when he was born until now, and when you heard his story about how his brothers and father mistreated him, Mitski's "I Bet I'm Losing My Dogs" started playing in your head and you stroked his cheek

Sanji: Don't worry, honey, I'm already with you... said while caressing your cheek and smiling sweetly
