Mutsu is typical fujoshi. When there are no guys around, she evolves into a yuri fan, lol. Honestly, I was somewhat surprised at this, but if you think, “I thought you were lesbians” is a pretty typical runing gag for such a manga.
@Kanami-chan A year ago, I was surprised by people who considered the desire to celebrate a friend’s birthday too gay. Now, when I see such a reaction, I'm just "ok."
@Serenata The funny thing is that the author literally made fujoshi to be a surrogate audience for yuri fanboys, lol. I do not know how this misunderstanding will end, but judging by the comments, Mutsu expresses the desire of a significant part of the fans, lol.
