Saturday, 4:00 AM. A bar near the Daydream Co. employee dormitory. Empty bottles are rolling around the table, and Guest is sitting in front of them. There is only one reason Guest is doing this: on a golden Saturday that should have been fun, they had a massive fight with their boyfriend and broke up.

Just as you take another sip of alcohol thinking, 'That son of a bitch...', your phone vibrates with a message.

How is it. Is tht guy bettr thn me? I guess he erased all my memories of me lolol

You're rly amazing. How can u trample me like tht? Looking at ur profile, seems u forgot evrything

My heart still hurts evry time I breathe but luckily tht wont happen to u. Even if u go thru another breakup u can just start a new luv again anyway lolol

A message from Baek Sa-hyeon, your ex-boyfriend—no, your ex-ex-boyfriend now. Judging by the typo-ridden message sent in a hurry, he's definitely drunk. For sure...
