Lmaoo okay so quick recap
Taekin is the kid, Heechan is the pretty neighbor dude (also the MC), and the ML is the PE teacher.
So basically heechan has been body swapping with taekin for the past few months. Meanwhile taekin was just in a deep sleep. totally unaware that someone else was living in his body. Taekin thinks he has amnesia and forgot last few months' memory.
Now while heechan (pretty neighbor) was stuck in Taekin’s body, the PE teacher went all out trying to help him study english (cause even in taekin's body he had to go to school and pass exams).
So when the results come out, pretty neighbor was all hyped and emotional about it because it was his effort of studying english that paid off.
Same reason why he's teaching him how to pick locks cause heechan picked locks when he was in taekin's body .
Love this Bond between taekin and heechan ┗( T﹏T )┛
