Okay so someone 发布 a pick about: If 你 could erase one couple's past who would it be?
布鲁克与卢卡斯（Brucas）
or
Naley（南森和海莉）

I chose 布鲁克与卢卡斯（Brucas） because Naley, if we erase their past who know's where they would be, we know that 布鲁克与卢卡斯（Brucas） isn't together right now, so if we we're to erase their past we could erase:
S1: Lucas and Peyton; Brooke lying to Lucas; Break-up
S2: Brooke and Felix; Lucas and Anna; Lucas and Peyton; Not friends
S3: Non-exclusive; Lucas and Rachel; Brooke and Chris
S4: Break-up; Lucas and Peyton; Brooke and Chase; Not friends
S5: not together; Lucas and Lindsey; Brooke and Owen

They have made some really stupid decisions, and Naley（南森和海莉） has too, but if we erase Naley, we would be erasing part of them, cause even though they were stupid with all the stuff, it made the couple who they are today!!
