The only difference, it will be the height and she got aproject about it.

Unconventional love interests melt their "owners'" hearts. In Choco Milk Shake, you have a man who's unlucky in love falling for his formerly deceased dog. In Anti Reset, a man who's never known love finds it in a caregiving AI. Both are sweet romances with odd plots.

- Similar vibe where one main character is trying to find the killer/culprit
- Interesting ways where/how the murders are being found
- Lots of background stories that are being brought back from the main characters
- Addictive and very good acting

Similar plot where main character is in a sort of limbo where they have insight into the enemy.
They use their human and more monstrous side together.
