I'm trying to recollect the name of a Korean Webcomic featuring a pair of (not blood-related) siblings who transfer to a new high school where they are mistaken to be dating. The female lead is some kind of delinquent and convinces her 'brother' to go along with this ruse. She gets into a lot of fights in her new school as well but bro helps her diffuse the situations. She seems to be afraid of/running away from another guy from her old school who is now pretending to date one of her friends.

I kinda lost touch with this series some time ago and I would love to catch up with it. Thanks in advance!

Hobbies include impersonating fictional characters and sucking on ketchup packets.
