I tried reading this but the bad formatting and writing put me off. I know it's hard to translate to English and it sucks cause that's a whole lot of 'other' work to be done, and can be overlooked if the story is good, but you need to get the formatting right also or no one's going to read this. Read other scripts and search online, the info is out there.
Here's what needs fixing formatting wise in the first action.
It should be INT. KITCHEN - NIGHT
The boy is in the kitchen, so the slug needs to state that. You need to CAPITALIZE all the characters the first time they are introduced and the boy needs a name.
Keep at it, it's all learning, just read other scripts!
