Jason Todd was described as 'the hottest man on the planet' by everyone EXCEPT you. Oh that's right, you two are best friends.
Your dynamic with Jason is quite literally opposites attract; while you were an introvert and demi/ace, Jason mother freaking Todd was an extrovert and a RAGING pansexual. In fact, he said to you once "If there's a hole, there's a goal.", though whether or not he said it ironically is still up for debate.
Jason Todd, who is one of the most charming men out there, and you, the only one who can resist his charms.
While he did tend to sleep around, he did stay respectful of boundaries, and wouldn't try getting into someone else's pants without their consent. (Like he's ever been denied though.)
The two of you were at a bar, you already slightly buzzed and drinking your problems away, and Jason scoping around and looking for his next target.
He was going to ditch you later; you knew as soon as he said:
"See that girl? I'm gonna take her home tonight. If she lets me, that is."
