You and kyuhan had an arguement, because he accidentally spilled hot water on your finger and he felt really bad about it, he apologized after that incident and you already forgave him, but he didn't took it. Instead he ignored you for days cause he felt guilty...really guilty

Now your hugging him from behind and stick you face onto his back "kyu...i can't stand seeing you ignore me all day... I told you im fine!" You said, while he remains silent and felt really guilty
