miya told kags that he's 'obedient', and that bothers kageyama. maybe he doesn't want to be someone like his old self again (ordering around self-centered king), but now, what he might be thinking/ bothering him is that 'he wanted other players/spikers to improve'. Kageyama is obedient because he just do sets that the spikers ask him. So maybe they're going to be some changes in his sets, changes/improvement from his initiative from what he sees a spiker can still achieve or can still do/improve. you know like how oikawa make kindaichi jump higher something like that.
and kags is awkward at conversations so... yeah. XD
i feel weird out of Kageyama, what happened i dont really remember ???..
