I forgot the name but parts of the story line goes like this. The uke is broke and has no money. He is on his last 3000 won and the side guy? Idk gave him his card so he can use it in a way it fit but when the uke for the first time tried to use the card that the side guy gave him the card read declined. The uke was excited to try a chocolate he had wanted to for the first time but since the card read declined he put it back. Ok im not the best story teller here but if anyone have come across this scene in a manhwa please let me know.
I can’t sleep because it’s keeping me awake
