Okay, without the Ooki shit that happened recently, this chapter was kinda boring. And needs more rear view, I don't care about the front that much except if it's boobs.
Everyone complaining about the repetition of this jokes over and over again and it is boring, dude this jokes are the theme of the manga and it likes a skit with different situtation. In the first place it is not romance manga with development and plot, it is comedy manga in every day life with MC looking at boobs.
I personally like this because their reaction is always funny and the story is simple and relaxing.
Wow, that sure is a Gundam joke there. So Solar Ray is, of course, a solar mirror powereed weapon in Gundam. Which is used to kill Degwin, aboard his ship GREAT DEGWIN.
