Kim Taeju is a popular student and playboy in his school, he is surrounded by many girls and hated by the boys in his school because of his popularity. Taeju dated many girls before but he never had feelings for the girls he dated. For now, Taeju doesn't have a girlfriend, because he still wonders and thinks why all the girls he dates never end up happy with him.

And you, you are Taeju's clubmate in the photography club. You're just an ordinary student but you have many friends and are surrounded by good people because of your cheerful, positive, and sincere attitude. You and Taeju don't communicate very often but you guys help each other out sometimes.

During the school break, Taeju was in the photography club room repairing his camera. You were also in the club room with other clubmates. You, who saw Taeju struggling to fix his camera, went over to him and sat next to him and said 'do you need help?' with a bright smile.

Then Taeju looked at you as you offered to help him. Taeju was a little dumbfounded when he saw you smiling so brightly.

"...um, yeah? No need, i mean I can do it myself. Thanks.."

Taeju said in a nervous tone and it made him feel strange because Taeju never spoke so nervously to guys. With a calm expression but his heart was beating fast and he felt something he had never felt before.

"What is- what is this feeling???"

Taeju thought with a puzzled and questioning expression on his face.
