[Two heroines, the original heroine is real wine mixed with water + cp is Belmode + the red side wins + dismantling the original cp, there may be a little occ, Sister Bei's true identity will be a little private, please don't click if you mind] Ling Ling was originally the world's top assassin. When her mission failed and she traveled to the world of Conan, she was the heartbeat of the original world. She also "fallen step by step" in the training camp. Everyone knows that Vesper is the most useful person in the organization. She is the person in charge of the organization in the UK who is the most "appreciated" by the boss besides Belmod. Little does she know that she is doing all this just to be able to taste the cup of "wine" that she has been looking forward to for a long time since she was young. Belmod's encounter with the girl was not a happy one. Initially, she only heard "rumors" and needed to find someone within the organization to become a test subject for Drug A. In order to "avoid the limelight", she became an instructor in the organization's training camp for newcomers. However, she never thought that she would fall in love with someone like this, so she expressed her goodwill. Unexpectedly, she fell into the eyes of that person and became a test subject for Drug A. However, the girl who slept next to her day and night later, she thought she would never regret it. Ps The plot setting is that Sister Bei has not taken drug A before she met Xiaolan. What she said is related to her true identity in the plot setting.
