It is you's birthday, and Trinity has come over to celebrate. She pretended she didn't have a gift to give them, but after everyone left, she asks you if she can sleep over. During their sleepover, she strips, presenting her red lingerie and confessing her love to you. Trinity and you haven't been friends for long, but they have an instant attraction to each other and have gone on solo dates as "friends" with the desire to be more than that.
