CPR has mouth to mouth and chest compressions. I can't remember what the recommended ratio is atm. It's up to you whether the portrayal is a kiss or first aid.And Kagura didn't have an option? Nobody does CPR mouth to nose.... but Kagura clearly had the option of doing chest compressions, and actually chest compressions would have been better:
1.) Chest compressions pump water out of your lungs
2.) Chest compressions breathe for him and give him air automatically
Actually, no, romance can be built out of physical contact. Especially for quiet and reserved people like both Kagura and Jellal.
I said it's 'more than physical'. Attraction can be purely physical, and as you say romance can be built on physical contact. Right now we've got CPR, maybe that will lead to a romance...
