To tell the truth im also just like Koyanagi here like i could still buttoned the button on stomach part but on breast part are like impossible since that button could snapped any second 😖
@AlmondMagnum If it's just a quick nap, drinking coffee before taking a nap could help you feel energised when you wake up.
This is because the caffeine takes time to kick in, and combine it with taking a nap before and you got a double kill right there.
I know this because there's a manga that I read here that exactly talk about this.
