Is this the second season? Its mean i read the king maker then i read this one right?

Yup

Hi! This is basically king's maker s2 mature version! It had the same storyline as the king's maker s2 in the normal ver, but this one has spicy scenes in it! So yes you should read king's maker first (the normal ver) for the s1 and if u want to read the normal ver of s2 too, and now s3 is starting as well. Hope this helps

Omgg thank you
