i don’t get it, what’s the significance of the jacket at the end

I think it might be something like “oh he really was planning to leave for good”

Because Uyun said he liked it so Jinhyeong was leaving it behind as a final gift

Jinhyeong left the coat Uyun liked as a parting gift, at the risk of catching a cold in winter. Both of them are so sweet

ohhh got it, thanks fam
