Ooh I picked a good time to read this. Last chapter just 4 days ago and it's a good final chapter resolution to this last arc.
... Now to bookmark and hopefully remember to check back in a year or so and hope there's a new arc to read.
I'mma be real upsetti if Tachibana doesn't realize there's nothing for him as a male and resolves to remain as she now is and for them to stop using "him" and start being more of a couple. Love romantic stuff (Second Life, Heroes Party, Angel Next Door, etc), and this nonsense about holding back gets extremely old really fast, if they keep doing it for another arc it's going to be a problem.
You can't go on overusing the same joke forever, this arc should have at minimum initiated the resolution to bring them together properly. I want to see them start abandoning the resistance and start having more cute moments, and by the end of the next arc they should be comfortable around each other and the stage advances to thinking about the future, where they had just settled on "this is things as they are for now, so lets go with it...", so the next arc is resolving "I don't want this to end"
