Vase Cannon Fodder Is Pampered by the Group Again Chapter -- Discussion

I feel sorry for original shou, the one before the transmigrator... I really wonder where he went and feel like the story would've been so much more interesting with him. I'm also curious as to how MCs parents would've behaved if transmigrator had showed up AFTER they accepted orig shou. Lots of loopholes and MC feels really flat like a piece of cardboard could've taken his place and nothing would've changed. I also don't really understand the behaviour of the adults around MC, technically they spoiled him to the extent that he behaved brainlessly in prev life, same as how the transmigrator is behaving right now. The only one I really feel is normal is the orig gong because I feel he's atleast making decisions based on his own observations rather than some brainless affection that has no origins...
