I have no definite information on when it will come back. You might want to keep an eye on official announcements or the creator's social media for updates.
The main theme of 'Gang of Highschool' manhwa centers around the growth and bonds of the characters within a somewhat rebellious high school environment. It explores their struggles, dreams, and the importance of loyalty among friends.
To become a god in manhwa, usually one needs to overcome numerous challenges, gain rare treasures or powers, and have a unique destiny or calling. It's not an easy path!
