Nah bro you’re confused lmao. It goes like this:
Jooha and pilwon fell off the cliff resulting in jooha having a head injury.
He wakes up in the hospital having no memories due to the injury.
Dooshik just takes care of jooha and they spend time together without jooha remembering.
Jooha chases after the dog that was too close to the lake, and accidentally fell in. Dooshik jumps in to save him.
During the scene it looks like jooha finally remembers hence why they made those faces and said that last part.
-
The memories were not lost due to the lake and they didn’t willingly jump in the lake for fun.
They did not have to do all that, falling into a frozen lake for what??? Now jooha lost his memories and u did this for what?
