If you guys want somewhat similar story I recommend this one: http://www.mangago.zone/read-manga/kamonohashi_ron_no_kindan_suiri/

Some things I would change:
— get the girl to be a bit more interesting and independent, maybe funny and let her train as some sort of athlete (gymnastic, judo, etc.) So she at least isnt so defenseless if she's stupid (which she might not be, just naive for now, but she isnt "brain" of the team, so let her be more then a "heart" cause that's cliche.
— get the creepy doctor out of the story (who wants to know a doctor can be a creep even towards dead bodies, who asked for that??? I'm so disgusted, why not portray Ted Bundy as good guy as well?)
— why is the new police guy (working for MC's police friend, a pedo) And why is that not addressed? He is grown man, the girl is still a student and he has crush on her??? Ew.
I like how plot is interesting, but the characters are all so annoying and un-orginal! And why isnt this tagged as romance when it obviously is!! Like, at least warn me next time buddy, I hate romance...
