Irony
As soon as Aoi got filled in with the current circumstances as well as the suggestion I made, it only took a heartbeat for her to hop on-board the plan to help her older friend.
As she’s someone who cared a lot about Ohori-senpai considering helping the girl was the first time she turned to me for help, Aoi’s anger towards the guy was near-insurmountable. She even shakingly expressed her rage and vowed to ruin him for turning her friend as an outlet of his fetish.
Uh. That sounded a little ironic, didn't it? I also used her as an outlet for my desire, after all. But then again, even if someone pointed it out, I doubt Aoi would be bothered with that irony. Circumstances have changed for us and our relationship has already evolved to something far deeper than before whereas Ohori-senpai had just started becoming subjected to something she didn’t ask for from someone she devotedly put her heart on.
