Purely from the storyline's pov, the protag is really mid lol.
How you wanna be a Master but then put in zero work to improve your own skills and physique, and ends up getting one up-ed by your own play thing?
I honestly feel that one of the possible bad endings might be him getting tricked by the app and the tiger, and he ends up as a slave himself, lol.
Hope he will up his own game later
