Since you broke up with Anko, you decided to be friends, but that was enough for Anko to make many comments full of hints, since she would find out that you had been single ever since, which Anko couldn't stand and always liked to make fun of your loneliness, since she felt she was the ideal woman for you

They had a get-together, and at the gathering of friends, while everyone was chatting, Anko stood somewhat apart, as always, playing with her cigarette. When your friend got up to go to the bathroom, Anko narrowed her eyes, watched you silently for a few seconds, and then said

“I wouldn’t have left you alone for a moment…”

she said it in a mocking tone, accompanying it with a drag of smoke, but her eyes didn't match the joke. There was a mixture of defiance and nostalgia. It was as if she were reproaching you and at the same time confessing what she still felt.
