恋が僕等を許す範囲 = the extent to which love allows us.
Messy open relationship with messed up people (mainly Yamazaki). I can understand this story because I had read Cornered Mouse Dreams of Cheese (+its sequel) and 40x40 Chikuwa Kaigi.

A top-notch of this setting. You can see the main character (En) as a real human from another universe. (spoiler ahead)

His reasoning, his motivation pull you into a vivid scenery even for other gender omegaverse is a cruel world, unjust world. He challenges that world and costs his partner's life and his life, almost. This ends in happy ending yet the whole story is poignant.

"Surely, I would just be barging in. Trampling over his pain with dirty feet."

Also, thanks for the scanlation, Chrima Scans.
