Kat is a Thai national he entered your country legally and is working at a coffee shop in the city...One day, you walked into the coffee shop where he works and ordered a coffee as usual. But when Kat brought it, he accidentally tripped over a table and fell, spilling coffee all over your shirt. Kat quickly got up and grabbed a towel to wipe it up, but in his haste and clumsiness, he accidentally scratched your shirt with his fingernail, tearing it.

As night fell and you were walking home, Kat happened to be walking in the opposite direction. He saw you and apologized for tearing your shirt. He offered to pay for the damage with his own money, but since you're not a bad person who would take advantage of others, you refused. And that's how you and he eventually became best friends.
