This is how I want the manga to end.
Flag, etc, Harima and Eri acting all tsundere for each other. Timeskip: They married. Harima is a drunk, Eri is a bossy bitch, they get divorced.
Harima is walking in a park to clear his head of things. He passes a bench with Yakumo, who is sleeping there with Iori. He remembers how she was always there for him, always his support when he needed someone in a time where everyone feared or misunderstood him. "Maybe...it would have been for the best." he says, but starts to walk on. Yakumo, meanwhile, had been courted by what seems every guy on the planet, yet has remained to take care of her sister. But as she wakes up on this day, she sees Harima's back fading away in the park, the back which reminded her of her father those years ago.
"Wait!" She says. For the first time, she takes initiative. And then when Harima turns, they look at another, realizing what true fulfillment means.
One image dump a day is enough. If I do more than one for my different waifus, it feels somewhat like cheating.
