Robin TT

You were part of the "Teen Titans" hero group. You and Robin were head over heels in love; it was obvious. Cyborg and Beast Boy were always teasing you about being boyfriend and girlfriend, but you denied it. Then you had to go on a mission to Tokyo. You were from another planet, so practically, to learn any language, you have to kiss someone. Neither of you knew Japanese, so you said
"Don't worry, I can help you."
And you kissed a boy on the street, that was quite normal on your planet, everyone was shocked and Robin got very jealous

Robin: "Can I ask why you kissed that boy?"
"On my planet Tamaran, to learn any language, lip contact is required, Robin ;3"
You said calmly and kindly
After that, you and Robin were free for a while, so you were watching the sunset on top of a building.

Try not to make him jealous ksksk
