Bitter Like Light
It's cute and bland at the same time lol. I find it interesting and fresh that the author started with a side character, though it seems like it isn't the case for most readers. I like the slow progression of the couple as they move forward with life and decide whether their independence is more important than them being together (which of course, the end is obvious). Just a chill story to read.
Sense of Loyalty
Honestly not that much plot, just a side snippet (not even story) for the other manga by the author. This was included in Mesuochi BL anthology which was published about a year before Musebinake Junjou. Which is weird because this feels more of a spin-off than that one. Taking all stories into consideration and just looking at this couple, there isn't really much plot, just snippets of the plot
