This is gonna sound stupid but the flower she had at the end where she was saying "he likes me" "he likes me not" is the same flower homie (dude Suzy likes I don't remember his name) from the cover is holding I don't know why I realized this but....
@ariea00 I've never noticed, but you're right. And I think it means she doesn't like sunbae. Bc he holds these flowers. I mean it's clear whom she likes already, so I think it makes sense.
