i think the voice... i feel like you give them this really nice balance of playfulness and awareness, but also capturing the perspective of your character so well... there's definitely a feeling of reading it and going "yeah this is a shin tag from lint" just from the sound/vibe

shin's thought process and his trauma and trying despite it all come through really clearly in a lot of the narration and it's very much a way that only you can capture

aaaa thank you twooo i've been rubbing my face in happiness

he really is trying so hard... every day i think about that one line where he's like 'doesn't feel great does it, doubting others?' he really is just doing his best and i love getting to explore that and that it shines through!

Voice, personality, and tone - I think you do a great job of really capturing Shin's voice in both the narrative and in his dialog, and the way that you word things really sets the tone where serious tags feel heavy, and lighter ones feel bouncy and playful, etc.

aaa that it it's captured in the dialogue means a lot to me, I worry a lot about that in particular because dialogue isn't my forte, I'm better at description or narration at least as far as what comes easier
it's good also there's that range.

something of all things chuubos pointed out and that i try to keep in mind while writing is that while trauma deeply affects a person, a person isn't ONLY their trauma so I try to like. balance things with him with that thought, so that he has that range as well
