This Manga is going on a direction that definitely surprised most people, but I'm loving the way the author has made Makino an actual consistent character.
She doesn't instantly know what to do when Maron has reached that point, but she also hasn't even sorted out her own feelings yet. Just a few chapters before she noticed that she was more interested in the "Office Maron" aka the more realistic and casual Maron(in her point of view)
A lesser author would've just made Makino find solutions that work instantly and would content most people, but instead it is made very clear that as much as Makino cares about Maron, she isn't perfect, like the fact that it still took some time to actually learn and pass the test. All her attempts may sound petty because, well, that's exactly the kind of character that even considered going to bed with a random person so Maron could rest.
Overall I understand a lot of people might be worried about Maron / not too happy about Makino's decisions currently, but they are very consistent with the actual character that was written, and I look forward to see the development of Makino and Maron as each of them figure out their lives (both individually and together)
