There isn't anything about friendship yet.
Shy and the girl Iko hasn't spouting anything about friendship power like those shounen.
The fight on chapter 3-4 basically to tense up that she'll be fine bearing another burden as in her fault causing Iko to be disabled following Iko past burden about her parents.
If you noticed the bar , there's like "0" casualties there.
Undoubtedly this manga will probably get really dark in future due the drama and stuff.
You would already notice it when Shy failed to save Iko properly causing her to bleed internally and some fractures.
MC only said something about some people exist to give her a courage despite being a crybaby.
This won't only apply to Iko but Papasha when Shy having a depression over saving Iko in chapter 1.
I wouldn't really judge it to be that cliche yet.
Though the real reason I was here was the subtext Yuri which is 100% obvious.
