The art is a bit stiff. While I feel like they've done a good job with the lighting and backgrounds, their facial expressions are a bit flat.
The script could also use a bit more refining. While I'm all for quick progress that doesn't drag out for a hundred chapters, things were going maybe a bit too quickly? I feel like I had a hard time following the timeline of events. Also, I couldn't help but laugh at grandma's completely incidental and not at all weird description of the protagonist's circumstances lol
"You enrolled in No. 4 middle school just to be with me due to my declining health. Because of that, you've not made many friends in the last few years. But now you're older and you should have your own life. Go make friends and have fun."
"Thanks, grandma, I had completely forgotten that I didn't have friends and that you were sick! Can I count on you to remind me of anything else I might have forgotten about my life? Hihihi~"
I mean, you don't have characters say things just so that the readers can understand the setting. It'd be a lot better if the grandma just said something like,
"Now that you're in your new school, you should try to make some friends, without worrying about me".
You'd still be able to tell that she didn't have any friends and that her grandma probably has some health issues, but at least it wouldn't be this awkward lol
