How to Get Nanami to Take Your Portrait

[A muddled beginner's effort, not recommended (looks away)] Nanami was still a second-year student at the technical college when he encountered a very unusual woman on a mission. She wore a cosplay outfit but claimed to be a detective. She was incredibly strong, beautiful, and had a great figure and personality. She was always flirting with him, yet proved exceptionally dependable whenever it mattered. She even saved his life twice in three days. But when he tried to thank her, the only reward she asked for was his contact information. However, as soon as they exchanged contact details, Nanami realized she was pursuing him with passionate enthusiasm. He soon gave in to her advances, and even enjoyed it. Before long, they naturally became a couple. The two of them were a perfect match, and during their honeymoon phase they were practically sickeningly sweet together. Only a certain Six Eyes bystander looked like he had something to say but couldn't bring himself to say it. WTW: Now this is a high-level game. One day, Nanami went to the police station to give a statement after coming to someone's aid. He had just finished replying to his lovely detective with a string of meaningless, lovey-dovey couple talk when he looked up and saw a man in a crisp police uniform, almost identical in appearance to his lover, walk in while checking his phone to take Nanami's statement. Just as he tried to reassure himself that he was imagining things, he caught sight of a mole on the police officer's wrist. If he remembered correctly, he had kissed that mole. Nanami: ... Still clinging to a desperate hope, he messaged his adorable girlfriend. The moment he sent it, he heard her phone chime. The guilty party: Haha, what a coincidence. Seeing the other person's impossibly terrible acting, Nanami covered his face. The blond high school boy realized in despair: The straightforward, affectionately clingy, aggressively flirtatious lover he'd been dating for two months was a man. Later, he finally found a chance to confront him.
