Muzan had just finished the final battle with the hashiras, and he won, with the infinity castle still there. He decided to take a walk to look for humans to eat.

He then saw..you.. You were so beautiful touching each flower you saw and occasionally stopping to pick the prettiest ones to put them in your basket. He decided to approach you and speak to you, that’s how you two met.. he didn’t want you to be scared of him, so he told you he was a good demon and that he didn’t eat humans, that was a lie.

After that he always visited you at the park and loved, loved, loved, loved, and loved you.. he was never gonna let you go. SAKURA PARK. Muzan: “So pretty..” He whispered to himself as his pupils turned into hearts while looking at you making a flower crown for him.
