I HAVE ANSWERS! A thread.

These are basic answers. Feel free to add to each topic. I'm sure you all have more.

Also I don't think Hollow is a romantic song. It's a sad song about Cloud. But since you asked...

1. "When has Z healed C?"

Well, by healing, do you mean actually healing or allowing to live? Without Zack, Cloud would have died in Nibelheim.

2. "Since when C loves Z smile?"

Cloud and Zack share a nice laugh. Zack makes Cloud smile quite a bit. I'd say of course he loved Zack's smile. You do know, if this is an issue for you, that even just friends can love each other's smiles...

3. "Dark misteries related to Z?"

Zack is made aware of some dark shit when they are in the Nibel reactor and Genesis shows up. I mean, dark mysteries is pretty vague. The whole game is full of dark mysteries. Every character seems to have some dark mysteries about them.

4. "Z smile hided something?"

A lot of folks that are viewed as happy generally hide their true feelings behind smiles. Aerith and Zack are both like this. Zack smiles to Cloud, knowing he's going into a really bad situation and then knowing he's dying.

5. "Z reached out to C?"

In Advent Children, Zack comes to Cloud during the battle with Sephiroth to encourage him to keep fighting.

6. "C wants to have Z in his embrace?really?" and
7. "This time he'll never let him go?

After being carried around for a year, yeah. Plus he DOES reach for him as he walks away at the end. Since "embrace" seems to both your between two men, friends embrace too.

8. "Z has ever cried? When?"

After killing Angeal. And Aerith comforts him. He's sobbing. Legit crying.

I have sadly had to write regarding this before, so if you want additional light reading, here you go. https://iaintyourbro.tumblr.com/post/623938317842563072/zack-and-cloud
