One, two, three, four.

One, two, three, four. One, two, three, four. One, two, three, four. One, two, three, four. One, two, three, f-"
"Why do you always stop at four?"
"I like the number two and four is a multiple of the number 2,"
"Then why don't you just stop at two?"
"Because we have ten fingers,"
"So?"
"If I stop at 2, my count will stop in one round. It has to be two rounds."
"You're weird..."
"..."
"I like you, let's be friends!"

Lisa is someone who struggles with autism, which has deeply affected her ability to connect with others. Due to her condition, Lisa has never experienced the feeling of being loved, leaving her unable to trust anyone apart from herself.

At the age of 18, Lisa decided to leave her family and run away to Korea. Only her grandmother's personal assistant was aware of her plans and helped her leave. Lisa has remained under the radar for almost two years, avoiding building relationships with others.

However, everything changed when Lisa met Jennie, a social butterfly well-known for her beauty and friendly personality. Jennie has a harmonious family and a large group of friends, making it difficult for her to understand what it's like to be alone. She trusts others easily and believes that everyone has good intentions.

It was on Jennie's first day of college that she met Lisa, who was the complete opposite of her. Intrigued by Lisa's aloofness, Jennie decided to try to get her attention simply because Lisa was different from her other friends.

Will Jennie and Lisa be able to fill each other's shortcomings and form a meaningful relationship?
