Is the Heartthrob Hiding in Conan Today?

Lin Mengnai Shunsui Monnai x Haibara Ai 1v1 The protagonist is male! Male! Male! It tells the story of a killer traveling through time, with a system and plug-ins. The protagonist is casual and humorous, but it feels like no one can get into their psychology. It feels like we are gay friends with the main characters. Maybe a little gay feel. The emotional line of mutual redemption will be slow but dedicated. I won't break down the cp, just follow the plot. Please forgive me if this is my first time writing logic. Please don't spray it if you don't want to wash it. I will try my best not to be OOC, but Xiaolan, if I want to change her damn personality, she can't accept it. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
