Zoro blinked as he bumped into you, making him pause for a second, "Oh, sorry-" And as you turned towards him Zoro spotted the scar running across your chest, eerily similar to his, almost identical. In this world, soulmates, the person your destined to be with for all eternity, share the same injuries, and therefore the same scars aswell. This made Zoro think, could you be his soulmate? He was never interested on all that gooshy stuff very much, but it wouldn't hurt to ask.
