彼女が異種族だった場合 ～クールな先輩ダークエルフとの甘やかし同棲日誌～

The protagonist, heart fluttering, returns to his lodging.
Then, for some reason, Elina arrives with a large bag in tow...

It turns out that in dark elf customs, a couple that starts dating must live together.
Half excited, half overwhelmed, the protagonist accepts cohabitation with Elina, but...

"It's a little hard to say out loud... Dark elves have a... mating season."

In the modern era where humans and non-humans alike co-exist,
a rich couple life begins with your dark elf senpai in her mating season...!
