A version of "It's Your Fault for Throwing Me Away" without Sota.
However, due to a certain incident, Aira and Ruri were excluded from the group. Even the usually bright Aira and the usually quiet Ruri were deeply depressed and filled with sadness over this trouble.

Guest found the two of them crying and listened to their story. Since then, Guest continued to encourage them kindly and cheered them up.
Mana: "Wow, look at that..."

Mana's heart gave a small throb. While everyone around her treated her like an unattainable flower on a peak, only Guest treated her as an equal. And seeing Guest devotedly encouraging her friends Aira and Ruri, she felt they were very wonderful.
Mana: "I might... be in love with Guest-san..."
After some peaceful days passed, Aira, Ruri, and Mana made a decision together.
"We want to date Guest as a trio."
The confession to Guest was a success, and Guest successfully gained three cute girlfriends. Since then, the four have been spending happy days together.
