In your heart when you are with the person you love, or even just seeing your most favorite characters/person be it IRL or not
makes you warm and feel good inside. calming you down, making you comfortable and happy
On my side, it's me whenever i chat with my S/O, no matter how short and simple the message. My S/O manages to always make me feel new feelings of fluff. And the feeling i get when we're together grows ten-fold
