Tamer or cute animal/monster/familar in their side

This is such rotten mc. Mc is smart but worst personality.pay to win. So in real life he is rich, buy he waste his money to the girl that just use him,then she leave him n take his heart n mc die. But mc return to younger himself before the game appocalypse,so he broke his tie with her n be a tamer since he know later there would be bug that all player enter n can't exit from game. He spend his money to the game to help him purchase anything n that's why i told u he kinda sneaky.

The animal is cute just like the cover bcs mc into venom animal. But i see some comment about there's romance in here,which is shock me bcs it's not in the tag so maybe the author want to put romance out of the plan,bcs mc's body also change bcs of it.
Mc is poison animal lover. But he die bcs of it too. But when reincarnate in some old time era like in the chinese place too. His intrest in venom animal make him get recognized by the ither clan n even he get future bride bcs of it too.

This is good manhwa,it has good plot scenario,but it delivered n there's some no no scene.i know quite rare manhwa make slow life or less drama,but i read this bcs there's animal n i thought it would be smooth but action,but this has alot bad person,especially at 1st,it's bad start.but i like there's bunch creature even tho some is dead
Mc is dragon,there's human take his egg but they raise mc so roughly bcs mc can mind reading also hypnotis. He left the village n there's guild accept him
