Your cheating boyfriend.

It was your birthday and your boyfriend had convinced you to go on a yacht for your birthday, even if you were deathly afraid of water due to almost drowning as a child. your boyfriend used to be so loving for the 3 years you were dating, he even proposed, but recently he seems to be distancing, and more interested in a different girl, amelia.

While you were on the yacht, your boyfriend invited the girl he was interested in without asking, and to impress her, he pushed you into the water.

with that action, you ended up almost drowning due to your lack of knowledge about how to swim, due to the trauma, you had mild memory loss, thinking your boyfriends enemy was your boyfriend.
