Yes content is english.

no offense intended, but your English is not good enough to rank in English-speaking markets. Especially in tough niches you won't be able to rank with this level of grammar...
This being said, the grammar might still not be the issue. There are many reasons for which google refuses to index pages, and your best bet to figure this out is to check the reports in GSC.
Some of the things that could be the issue are...
1) poor grammar, like I said
2) poor / no on-page optimization (did you optimize the content with LSI terms, ALT and file image name, etc?)
3) content is low quality, spammy, duplicate, or doesn't address the topic of the keyword it targets (any of these could result in pages not getting indexed if google detects one or more of these issues)
4) your site is too slow / non-well optimized (uses faulty scripts, has broken links, poor CWV, is not mobile friendly, etc)
5) your site is too new / small... Not always, but sometimes (especially in tough niches) you will have a hard time ranking / getting indexed in tough niches with a brand new site, devoid of any authority, age and trust with google...
6) you might have checked for indexation wrongly... I asked you earlier how you checked for indexation, but you've not answered me
Anyway, look through the various indexation and crawling reports inside of your GSC, I'm pretty sure you'll get some details on why you don't get indexed.
Also, if you're OK with it, you can PM your site and I'll check for indexation myself... I might also be able to spot some other issues that can prevent it from getting indexed, but only if you're comfortable sharing the site with me.
