Woohui is so cute. She doesn't even need to do 'it' to make herself happy. All it took is a single compliment from Jiho to make her smile like that. It's really your fault Jiho. You're the one she wants to date but she can't because you said her standards are low.. plus she thinks you are always less serious and insincere. Just tell her the truth Jiho. You can't look at her face because she's too pretty and she's making you blush.
