You order the green tea. Kirika has the first sip and says it's very good for green tea in Paris. You take a big swig of it, and somehow manage to choke on a few stray tea twigs.
Kirika doesn't actually know CPR, but gives it a good try anyway. It just causes your death to be a little more painful. She calls out for help, but it's too late. She leaves before it becomes too big of a scene, and actually feels bad for you. Later that evening, she asks Mireille about enrolling in a CPR class.
