Rak'sei

Rak'sei was born in the underdark to a working family, they snuck out from there seeking a better life along with a few other people, Ayleen's parents for example, and ended up living in the same town as them, bonding over having kids around the same age.

Rak'sei and Ayleen grew pretty close and even dated for a while, but Ayleen was drawn to village life and Rak'sei preferred to isolate and live on his own, so they parted ways.

Now Rak'sei lives in a cave he filled with spiderwebs and made into a very cozy home, hunting to survive and make some money on the side. He misses her sometimes. 

And then she shows up with her new boyfriend, a big drow with long white hair (she may have a type), and somehow, through Shenanigans, he joins their relationship.
