Review Detail of StaidLynx in Akashic Records of the Bastard Child Engaged to a Goddess

1st volumecharactermc is op but it feels like he's a side character.he lacks character/maturity(it feels like he's weak).he questions everything.No character development even after getting massive plot armor/his mission practically no change in mindset.serena(his summoner) really feels like a summoner with no character,she doesn't have the aura of the main heroine(doesn't spent most of the time with mc)much like the mc.in simple terms their characters needsplotmc spent 10 yrs studying but it yielded no results as he utterly failed at his first deal(quite disappointing).Mc past memories haven't resurfaced.mc stats were upgraded to rank A but it stills feels weird as he spent a day to upgrade his first skill from rank f-c,but takes 10 yrs to upgrade most of his skills to rank A/B. he's group oriented.still not used to blood/death but he killed the goblins.(he freaks out too much).still not at school while he's 18yr old.overall the 10 yr time skip crucified the mc development stage(encounters,battles,leveling,academics,romance,maturity etc)well I'm hoping for volume 2 there's change
