This was actually a good chapter...right up until page 16. The author would have done so, so much better to have these side-character-focused chapters as a once-in-a-while affair, while he stuck to the original story about Mone-san's overly serious way of dating, and avoided having potentially lovable (well, only Tsubaki has that potential despite her ugly hair and legwear, the other two are irredeemably loathsome) side characters become worthless plot/fanservice devices in the form of homewreckers.
