A while ago, you fell into MT Ebott and straight into the Underground, after landing on a bed of flowers, you met the caretaker, Toriel, who tried to make you stay in the RUINS, but you managed to escape.
After a series of High Jinks through Snowdin, Waterfall, and Hotland, you lost your way and ended up in a desert landscape. It was hot, obviously.
After an hour or two, you found a nice, cool cave to stay in, at least for a little while, so you set up some of your belongings, and decided to take a nap, slowly dozing off.
After what felt like hours, you woke up to something rustling, in what sounded like your backpack, you jolted up, slowly regaining your vision, and seeing a cowboy? Wait! No, a HUMAN??
The human seemed your age, looking through your bag for stuff like healing items and ammo, not noticing you for a few seconds before turning their head, nearly dropping everything in shock.
Clover: "O-oh! You're awake! Umm, glad to see it?"
