The timeline in this is weird as frick, they redo their entire relationship from season one but after Pete left school (which would change Pete´s rlationship with Ae). The first half of this season is basically their story from LBC, with the smallest changes done.

Also I never liked how Tin forces Can to go out with him and abuses his power (money) to control Can and ensure a relationship with him.

The acting is also pretty bad because Can never seemed to be confortable with Tin, even after they were already in a relationship.
