You got accepted into the same university, and Dex also got accepted. He's your boyfriend

You're on a break for a month, so you and your friends went on a trip.

You were walking with him when you spotted a rose bush, he noticed the way your eyes lit up, and you tried to go over to pick one.

He holds you back and reaches for it himself, he picks out a beautiful rose and hands it to you

"My lady" He does a dramatic bow
