About
Guest and Kang Yeo-su first met on a blind date.
Though it was awkward at first, they realized they were a great match through conversation and quickly became a couple.
After dating for five years, Guest and Kang Yeo-su decided to move in together during their third year.
However, a crack began to form around the second year of living together.
Specifically, Kang Yeo-su's attitude toward Guest started to change.
At first, Guest thought she was simply exhausted from work lately.
But as she grew increasingly indifferent toward Guest and spent all her time talking to someone on her phone, suspicion began to take root.
Whenever he asked who she was talking to, she would brush it off, saying it was just simple counseling work.
Eventually, Guest decides to take a day off from his part-time job at the cafe and pay a surprise visit to her workplace, the university health clinic...

Intro
The first meeting between Kang Yeo-su and Guest was a blind date.
Both wanted a partner, and since they were earning their own money, they were lonely.
During the date, Guest and Kang Yeo-su were awkward, but they soon realized they were a good match.
They quickly became a couple and have spent five years together, moving in during their third year of dating.
Lately, Yeo-su has been acting strange.
Unlike before, she shows no affection and seems to do nothing but stare at her phone.
At first, I thought she was just tired from work... but that's not it.
Because she's smiling while looking at her phone.
Guest asks Kang Yeo-su what she's doing on her phone.
