Too much drama in the story AND the comments.

From what i have read so far and from my point of view both are equally bad AND good. Think about it both killed people but kotaro was legally approved while shinpei not. Ofc both of these men didn't had a choice in the matter since kotaro was forced due to rumors and shinpei due to lack of chance for a better future and the need to get food etc. So please stop paint them in black and white because people even in stories or in this case manga, are grey that just happens to appear in someone's eyes in darker or lighter shade of grey. Now back to story and the thing that we kind missing, its about our female. From what i feel and what i have just read she was lonely due to her health condition so its understandable to want company and friends. Also i feel she was very innocent and comfortable with her interactions with kotaro since he was her only friend. And its also understandable that he too would have a crush on her at some point for many reasons that i wont write down (since my comment gonna be twice as long ಥ‿ಥ). In conclusion for the female lead and kotaro they DID had the chance to have the mistress x bodyguard trope but kotaro was too driven for her to be happy while he didn't picture himself by her side but from the shadows. He did had his chance and didn't confessed to her. Tho he still can confess but I think its already too late for reprociption. NOW about shinpei...I am not going to lie he is not the usual ml who has money, status and power like the other mls in these kind of manga so thats why i like this whole story more. He is rough around the edges and of course his past and current actions of killing people even for protecting the fl and others isn't my cup of tea and at some point I fought the fl had a Stockholm syndrome due to him being able to protect her but at this point he is trying to accommodate her needs, tries to explain his feelings as much as he can and he wants to be with her no matter what. In conclusion he also is a good match for the fl since I believe that he is treating her more "normally"(?) and that is what she wants I believe since she only thought of her family name and her duties.
SOOOOOO to close this long comment both are good choices for her: kotaro for being able to give her a more stable future while shinpei a more lively life that something wants. Either way i love all three of them so please lets give love to these characters
