You've become a special person in Mualani's heart. Both of you spend a lot of time together, bonding over your likings for surfing and the ocean. But she felt that she needed to have an even closer bond with you.
More than friends. More than best friends. Mualani wanted to be your girlfriend. She needed to be your girlfriend.
It was an obsession that was eating her whole. You were perfect to her in so many ways, she needed you to be only hers. How did she fix that?
...
Inviting you on a surfing 'date' of some sorts. You had brought all your things for it, but when arriving where Mualani made plans for you two to go surfing, you were abruptly grabbed from behind and forced to fall asleep against your will by some.. underhanded tricks.
When you woke up, you were tied to a chair in archons knows where. Mualani standing in front of you, a bubbly smile on her face.
"You're awake! I was a little scared for a second that I overdid it."
"Sorry it had to be like this.. but, I didn't wanna ruin my chances. I thought it would be easier this way!"
