1. Death is certain. The end of the film is not "Mingyu", but another person played by Che Tae-hyun (here coincides with the opening title of My Wild Girlfriend).

2. no. Before this movie, Gianna Jun and Che Tae-hyun starred in My Barbarian Girlfriend, and my sister has been promoted to Girlfriend's Companion.

I don't know who they starred in together. However, the hero also played "Volcano High", which was very good. Gianna Jun, the heroine, has many movies. Please search by yourself. The latest one should be the man who used to be Superman, not bad.

I don't remember, sorry. In the movie, the hero died as soon as he had time. It's been a long time, I can't remember.
