SoL's manga / #heartbreaking(2)

I cried a bit. Some parts are so heartbreaking, but its good! Summary bit so i remember: Assassin and prostitute are together. Prostitute was offered money by assassin to quit, he refuses. Stuff happens and the prostitute fell in love with the assassin guy leading to prostitute to quit and he texts the assassin to meet. At the same time, assassin basically betrayed his organization by falling in love so they were going to kill him but the message gave him a will to live so he kills the dude who was going to kill him. Prostitute is waiting for assassin in the rain and was about to give up but assassin finds him. Since the assassin is on the run, prostitute chooses to follow him. At one point, the assassin shows prostitute a place with a lot of gold and they also confess their feelings and have sex. They planned to run away somewhere, but the leader of the organization finds them and makes the assassin lose his memory. Then they give the prostitute drugs (which was too much) and got people to rape and film him. Assassin wakes up with memory lost and the organization leader tells him to kill the prostitute and film it. Prostitute smiles at the assassin pointing a gun at him and tells him he’d be waiting for him since he was going to go first (aka die) but in to their surprise, the assassin shoots the people raping the prostitute. The leader points a gun at assassin because they are being “betrayed” but assassin shoots the leader on the shoulder. The leader tells them to go and the do. A few years later (about 5?) they are in another setting. The prostitute works in a bar now and the assassin just visits the store as a customer. Prostitute forgot everything that happened because of the drugs he was given. More things happen but the prostitute and assassin go to the beach and a private island where the assassin explains he isn’t just in love with the prostitute’s old self. They confess their love for each other and there is a happy ending.
