The comedy,the mystery (quite predictable but still surprising),the characters,the story,the art,everything. It's detailed and not so cliche. What I love about this manga is that both the guy and the girl understand each other,there's no need for misunderstanding drama or jealousy in here. Teru's type of female lead is very rare,I mean which girl would shows her navel? That scene made me literally lol. So she isn't the one who needs protection and do nothing. She can't fight,but she knows what to do and she gradually changes (she learns about what happened and not going to let it happen for the second time). She cries too,yes of course but there's a meaning behind it. Not just because she's hurt because the guy left him or blah blah in the typical cliche shoujos. She cries,then she tried to stand up again and look for a solution. She lets herself became a servant not because she's bullied but because she owes something.
So about Kurosaki the baldie,he went through a lot in the past. Well anyone would feel they have an unforgivable sin if someone died because trying to save him,someone he loves,someone who for the first time understands him. The story? I would say perfect though there's still some parts that's left hanging,like 'who threw tables to Teru' or 'why did Sou suddenlt has cancer' It's not so important but I'm kind of curious so it bothers me a little.
About the bad-guys (antagonist) characters,I love how Motomi Kyousuke made them bad because they had reasons. After all everyone is a human,there's no way that someone's bad just because she/he wants to be bad. There should be a reason. Ex : Rena,Takeda,Kiyoshi,etc.
Anyway it's recommended for those who're looking for dramas and mystery. This is good and hilarious. It's neither boring not cliche. It feels real and cute at the same time.
You can't find cheesy misunderstanding in Motomi Kyousuke's mangas,all of her(his) manga's characters understand each other.
