Henshokuka no Kawaii Akuma
It has a very similar feel to both Yamamoto Kotetsuko's Konya mo Nemurenai and Umino Cana's Uchuu De Ichiban Kimi Ga Suki

The one thing I couldn't appreciate was the mangaka's afterword. Enzou's practically bashing Yato for crying because he's a "man" and not a "boy." As much as Enzou will attempt to say at the end that crying may be uncontrollable because they'll sometimes feel that way, why even try and question and criticize your own character for doing it? Just leave it at the fact that all your stories seem to have someone crying in it, regardless of the genre. I just found it unnecessary and ridiculous. After all, crying is an ability pretty much every human has. Trying to restrict it to only a few selected groups is what is truly inhuman. Leave the poor men of the world that need to cry alone. Nevertheless, I won't let this impact how I rate the story (since it's not part of the story). I just needed to point this out.
