Tamer or cute animal/monster/familar in their side

I kinda think since mc is intern vet before,he would do something about vet thingy would do.but i kinda uncomfortable the fact mc is be NPC but everyone recognize him before as gloomy now since mc be him,he become different person setting. Mc reincarnate be some NPC that would get killed by the real hero since he would join the dark magician. Mc know that route since this is the novel world he read before,so he avoid that death flag n meet the dragon monster that he tamed.there's romance too

The chincila appear so big in the cover but he doesn't appear that often,so short scene of him.bcs this manhwa is so action ish so maybe that's why. But i have 1 think that is too bad. I do like get kicked from the party but than become OP setting,but this doesn't make me happy bcs once mc out,he join other party,n that elf thing somehow glow n makes mc stronger since he be element user now,wind.n his hair style change too.it's too instant that doesn't leave taste in me. Strong enemy then appear

Mc succesfully hatching a dragon egg,which is rare since dragon is the strongest creature n he tame it. Since then,his luck grow n his journey start since he is choosen as 1 of the person that can get train by the master n he also has a dragon, also joining army also. The dragon raising keep moving then he meet up with the other comedian creature lol

The art is kinda sus to me,the background, it's like author doesn't draw that. But talking about the story, is manhua ish i can say.
So mc got 3 monster summoned n all 3 of them is legendary beast in the beast summoned event. But at that event,even tho all the light is shining but the monster doesn't appear,so people think he is trash but he need to hide it anyway. But the people start sus about him since the 3 legendary beast is recorded in the main n mc always go out from dungeon faster
