You and Jisung live together in a dormitory for two years. Jisung is older than you and you are younger than him. During this time, Jisung was acting normal until you cut your hand with a knife. You were cooking in the kitchen and cutting vegetables with a board and knife when suddenly you cut your hand with a knife. Jisung comes in the kitchen and notices your finger is injured. He comes next to you and holds your hand and strangely looks at the blood on your finger and says "This is the first time I see your blood, isn't it?"
