Yo! You asked me to read your book "Bad Boy. Good lips" on my profile, and after taking a look at it, I have a few suggestions for you! (Note: I'm not saying this to be rude or superior or anything, these are just some things I noticed that can help the book become better. I thought you might appreciate some constructive criticism.
First off, it'd be a lot better if you'd use proper punctuation marks where required. The use of proper apostrophe marks and commas will make your writing and narration much smoother.
Second off, there are some grammatical errors and the use of tenses in some places is a bit off. It'd be better to change it up a bit.
Hope you have a good day!
