the plan is good, but if it's too slow it'll get boring for a long time, at least there's a time skip, not too long in elementary school (sorry, I've only read about 30 chapters, maybe there will be a time skip in the next few chapters, I don't know)
I just hope the author doesn't change the character's personality suddenly, but gradually so that it seems reasonable that the character changed because of the butterfly effect of the chat group or other external factors.
