Measuring the Finished Shape of Overlapping Laths | Which Two Points to Choose
Hello, everyone. It’s Enta here. My senior from Kyushu went back home the other day, so I can finally breathe a sigh of relief, lol. I’d be happy if you guys had a good time, lol—even though we were just drinking the whole time.
