aww this episode was so painfully realistic. i really like this manga. i wonder if glasses senpai isn't used to thinking romantically either so he didn't act on anything too deeply?
I like how the author didn't portray him as an a..hole, but, kept some ambiguity to show he acknoledge her charm ! So, maybe e wasn't interested in Yuzu àd just spoke without realising the possibility of misunderstanding.
him probably: "I complimented her closest friend, she must be happy"
her: "I am ugly, he would prefer to be looking for books with Yuzu, romance isn't for me after all, why i'm even trying"
