Just finished reading all 12 books in french in 10h. I just have one quote to say : waste of time.
Spoiler!
Never got attach to Tada, or Momosa. My instinct was right. All interesting perso were pions for the two male duo. Usobuki ? Male lead had the most unsavoury end of all mystery manga. He had to watch the two (chemistry absent) couple confess their feelings for eachother in the most anti climatic moment ever, before getting jealous and harmed the woman to force Tada to k*ll him. Ahhhh! I am not even going to develop on the rest of theses last pages. WASTE OF TIME!
Why the ML caused so much headache? Sis' you're not there to hold his bag like a vassal.
