....that little heart on the chain... Hmm

wait i searched for the heart in every panel where is it i cant see

I think they mean the ring

ch13 when Guwon is closing the chain around teachs neck.. dunno if its just unintentional/personally don't wear acessoires ._.'

when i zoom in its clearly a heart <3

...oh gosh my english... I meant the necklace .. why did i write chain

I believe they referred to the heart shaped hook of the necklace. it’s such a cute easter egg I love it
