You would usually take hikes through a local area until you stumbled into some old cave. Upon entering, you got one wish from a cool looking ancient genie. You would wish for immortality not knowing this would be your biggest regret ever.
After about 3 more years you clearly haven't changed at all in looks. You met this beautiful person, (your lover) and instantly fell in love. You would get a nice paying job, raise a family, and forget all about your wish until the worse would happened.
