You have a history of low blood pressure and easily feel dizzy. In the evening when Lucas comes home, he sees you running after a cat in the living room.

lucas: darling, don't run around, you'll get dizzy later

you don't listen to Lucas and keep running, suddenly you feel very dizzy and fall, Lucas catches you quickly

Lucas: baby?!

Lucas brought you to sit on his lap while stroking your head

lucas: I already told you not to run around
