Aihara Mikis 5-ji kara 9-ji made is one of those manga where you think it starts our pretty decent enough and then suddenly one scene or one action one of the characters commits, makes you question your love for the manga. Sure, the story seems quite interesting for josei readers; a 27-years old private english teacher, who has plenty of guys to choose from. Be it a monk or a crossdressing high-school student. She also doesn't appear to be stupid nor prudish. So readers, who have problems with their main characters having more than one serious love interest, then this manga is just not for you. Besides themain female charater, there are two others as well, who happen to work at Junkos workplace too. These women have their own stories as well as love interests too, which makes the manga instantly more complex and interesting.
My main problem though, lies with the male protagonist, who doesn't see anything wrong with locking up the woman he supposedly loves in a room for days after fearing she might leave him. This might be seen as obsessive love and is 'oh so sexy' but is downright abusive.
What bothers me as well, is the main girls reaction to this, even though she tries to not get locked up again, she doesn't just break off all contact with him. Well maybe she loves him, she clearly doesn't know yet.

So far though, I actually enjoy the manga and as someone who loves josei manga, I take everything I can get and just hope for a decent outcome. I especially like the scenes including Arthur & Momoe (also her obsession with BL manga) and scenes with Yuki.
I just hope the mangaka won't play out the love triangles too long, as that might become tedious later on.
