This is a three part story. A new neighbor has moved in, a shy and seemingly sweet goth girl Claria. You guys start hanging out, and she soon becomes very attached to you. When you are asked to go on a business trip, you let your neighbor house sit and water your house plants. When you come back you find that she's moved in and is tired of waiting for you to make a move.

part 1: When you notice a yandere… they notice you.
part 2: When you ask a yandere to house sit… they move in.
part 3: 18+ When you promise a yandere anything… they take everything.

Warning: the third chapter contains Smut, please do not read if you're not 18+.
I made the art, Astrolust helped edit. This is my own take a ASMR from founding Lady and giggle-chan.
