Hear me out. I think we also need to stop naming everything rape.
You and me both know that Sena is strong enough to push Mikagura away and secondly hate sex/pity sex also exist. Sena felt bad and intentionally let Mikagura have his way with him. We can have a discussion on how bad it is to have sex when you're mad or in the middle of a fight or have sex out of guilt but let's not call everything rape. Just my opinion. Sena wasn't hurt, he wasn't physically or mentally traumatized after we see Sena laughing and having a heart to heart. Not ideal, but not rape in my opinion.

If some of you struggle to differentiate grape and not here's a list for you:
Jinx - grape
Hatsukoi note - grape
Hatsukoi note 2 - attempted grape
Kono te wo hanasanaide - attempted grape
Guinea Pig wa Ori no Soto no Yume o Minai - grape
Profundis - grape
Married man - grape
Down fall - grape
This list unfortunately can last forever.
But
I don't get the vibe that Mikagura is grasping Sena. I also don't think that there was grape in Afterglow. Find a way to deal with it without wishing harm to people, otherwise you come off the bad person.
Can we normalize not raping ur partner when ur mad
