the design looks nice and at least it means something to you- but as said already- be very cautious about getting something related to a partner permanently inked on you- costly to remove and can be a seriously painful reminder if ( for any far out reason) things dont work.
As for pain, it feels like a pinch or a bad scratch- but this stops the minute the needle is lifted, and after the first initial “ow” can actually be quite pleasant. No worries and have fun!
