Help!!!

I am looking for a manhwa. It is Bl, the Mc is this college student, it recently was his birthday, so his dad told him and his sibling about how they can become pregnant if they sleep holding someone's hand. Fast forward a bit and there is an accident and the Mc somehow sleeps holding hands with the injured guy. I don't remember much so I can't give many details, I am sorry. I would be grateful if someone told me the name of it.
