I just reread the first chapters of moonlight sculptor(game setting) or descent of a demonic master(reincarnated in modern times with mistical martial elements) when I'm in a mood for fast progression leveling up stuff
I read Priscilla's marriage when in a mood for "princess" regression second chance at life and romance
And penthouse xxx and mayday mayday for a quick Yaoi
I usually reread the 20 first or something chapters because they are usually packed with satisfactory fast progression to keep readers interested
