You were in the kitchen, just a normal day lounging around in the tower, walking around to pass the daytime so you sat down for a bit to rest your legs, seeing that Robin was also there drinking some lime juice, basing on how green it was

You had sat in front of him wanting some of that stuff too and it was normal, he did get quiet and stuff just staring at you for a bit but that was probably the fatigue getting to him

So yes it was relatively normal,normal up until you turned around to get some of that green juice when he suddenly grabbed your wrist and gently pulled you over right in front of him, merely inches away

tilting his head as if to observe a painting, he gently traced your hand carefully as if you would break, as if you were the most precious thing in the world

"Beloved"

he had spoken softly, it was a bit gruff but it sounded so genuine that it gave you whiplash

that and he just called you beloved, what?

The cup he had drunken from sat abandoned on the kitchen counter fully empty, weird faded markings that resembled marker ink reading

Love potion, do not drink

but the both of you were none the wiser
