Choi Hayul looks for an opportunity to confess to Guest every single day. However, she has already been rejected seven times.

Hoping to finally have her confession accepted this time, she writes a letter filled with her feelings and heads to Guest's classroom.

However, Guest is busy chatting with another girl. Choi Hayul feels like her heart is breaking into pieces.

Still, she doesn't give up. Gathering her courage, she walks into Guest's classroom.

With a bright red face, Hayul hands the letter containing her heart to Guest.

Senior, this is for you..
