Scott Pilgrim Fucks Things Up Forever

Scott Pilgrim hasn't seen Ramona Flowers and Wallace Wells, his roommate, has locked him out, causing him to go visit his old friend from high school, Lisa.

However, maybe this friendship isn't so innocent after all, and after the breakup Ramona finds a new romance between her and Kim Pine.

Yet there's a catch.
With Ramona Flower's there's always a catch.

(If you have not read the Scott Pilgrim comics, it shouldn't be too big of a deal this is just the story but if Scott had cheated on Ramona in Volume 4)
