Lovelessboys8's Manga

I really loved this manga but the ending was very unsatisfactory imo, just felt like there was so much more to be tied up, jeahas death felt forced and then youseb just murders random people whilst having no serious reaction to just accidentally killing the only person he values??? Would've preferred an ending where he killed every main character bc it would have made more sense. Then the investigator looking just like jeaha ?? Like the author knew the end wouldn't work if the character wasn't shoe horned back in there somehow.. why even have such an intense set up between yura and jeaha just so they can get absolutely no closure ? Idk like I said I loved the premise but the end could've been so much better
