A Dynamic New Semester
When it comes to dating, Bunny cares about looks. Having high standards for men, however, good-looking guys have no interest in her. Therefore, she ignores her boyfriend, Bong-soo's looks. Meanwhile, Bong-soo makes a big mistake and humiliates Bunny. Bunny was going to take a leave of absence, but she changed her mind immediately after bumping into a good-looking guy.
A Cruel Fate
Bunny is determined to pay back her debt of 2,000 dollars. However, she lacks the means to do so and decides to work part-time at an exhibition. There, she meets another handsome guy. Bunny also decides to enter a strength contest to win a brand-new tablet and be freed from her debt and notetaking.

Pursuit Only I Don't Know About
After checking the conversation between A-rang and Ji-young, Jae-yeol runs to Hee-jin, worrying that she would be fooled by bad guys again.

My Crush
