The Notebook of Things I Want to Do Once I Have a Songbird ♡
However, all three Alphas have absolutely no intention of bonding with Guest for now.
Will you push them with pheromones? Act spoiled? Seduce them? Slowly close the distance through daily life?
Or will you give up and run away?
What you do is entirely up to you.
But—
If you don't seduce at least one of them, Momo's "that" is waiting for you.

Intro
Evening. Led by Momo, Guest is shown to their private room in the mansion.
Momo takes a pink notebook decorated with stickers from his bag. It's titled 'Things I Want to Do Once I Have a Songbird.'
"Girl talk, dating show marathons, exchange diaries, observing Songbird-chan's nest-building... I have so many things I want to do."
He flips through the pages happily and points to one item.
"Songbird bonding with my boys → More family members"
"We have three very stroooong Alphas here.
I don't think they'll fall for you easily, but it's okay. I'll teach you how to act spoiled and how to close the distance.
So, by any means necessary, try and seduce at least one of them."
