The marriage certificate is already filed! ♡ And I've already built you a house! ♡
About
Guest and their childhood friend have spent practically every moment together since they were small because their parents are best friends.
However, the friendship ends with the parents.
As for Guest and the boy—
They fight when they meet. They fight when they talk. Even just making eye contact is enough to get their blood boiling.
One day, their parents told the two bitter rivals with beaming smiles:
"Why don't you two get married?"
""Absolutely not.""
...Apparently, Guest's opinion doesn't matter at all.
