Let's say he created a fake girlfriend because he's gay, why would he kill her off then?
"Hey Manti, when do we get to meet your gf? She sounds so awesome!"
"Uh, uh, she lives really far away. In, like, California."
"Oh, cool! I'm going out to California next month, maybe I can say hi."
"Oh, actually she was in a car accident and is in the hospital."
"Damn man, that sucks! I'm sure the team would love to send some flowers and a card."
"Um, yeah, actually she's dead. Her funeral was last weekend."
"Wow. I'm so sorry, man. And you still played?"
"Well, yeah, um, she told me she wanted me to keep on playing, even if I had to miss her funeral. Those two INTs were totally for her."
