Summary
Aya Oosawa has a crush on the guy who works at the record store she frequents in Cardiff's Castle Arcade. Little does she know, the rocker boy behind the counter is actually Mitsuki Koga, the girl who sits behind her at school! As the two bond over a shared interest in Japanese music Mitsuki's dual identities threaten to crash into each other when she invites Aya to a concert under her assumed identity.
A retelling of The Green Yuri in which Mitsuki and Joe did move abroad when she was little and the successive events unfold ever-so-slightly differently as a result.

Summary
“You say everyone hates you. Is that really true?”
Silence. Then, finally:
“The people who matter do.”
“Who are these people?”
“My ex-girlfriend. Aya.”
But she wasn’t done.
"And…. that other person… “
She finally looks up.
“It might be Me.”
———
Mitsuki starts therapy.
She says it’s to feel better. To process the breakup.
But the truth is—someone else in her body wants Aya back.
Intimacy doesn’t come easy. But if it’s them, they’ll find it—
(A love story. With therapy. There’s a happy ending. But like everything, it just takes time to get there.)

Summary
Mitsuki supposed everyone had something they had an irrationally ardent interest in. She wasn’t that self unaware; she knew that to a lot of outsiders, it looked like she was utterly obsessed with music. That was fine by her. Everyone had their passions.
It was just—she never expected Aya’s passion to be pumpkins.
(Aka: author felt the first fall breeze and immediately needed to write Mitsuaya Halloween fluff. <3)

Summary
Mitsuki lives in a gigantic city that encases the entire earth, as does everyone else in different parts. Trees don’t exist much anymore, we have countless photos and videos but nobody’s really seen or touched one in person in a long time. Oceans make all the oxygen now. And it’s everywhere.
She goes to high school, Aya plays on the soccer team, she frequents the field a lot. They don’t really know each other.
But the thing is they do.
Since grade 9 mitsuki has been falling asleep every night and reliving the same day in the same place, but 350 odd years ago.
All the same people but the buildings, animals and landscape entirely different. It feels real. Except in this world her and Aya are friends. Or something like that…
What to do when the girl in your dreams isnt a dream, but the same one in your time, and neither of you know it?

This was originally written with random characters, but it fits so well with them that I just had to.

As the sun rose and softly poured in through the cracks of the curtain, Koga Mitsuki yawned as she stared upon the album that she had been working on for days. weeks. months, even. It was complete, finally, the deluxe version of “Me to Her” that she dedicated to her beloved darling : Oosawa Aya, to just show her how much she meant to the guitarist.
And now, she just needed to make sure that Aya listened to it, in the most special way ever.

Summary
If Mitsuki was the protagonist of a shonen manga, she probably wouldn't have thought twice about taking a swing at a guy.
Or:
Chapter 138 but 70% of it is spent on exposition in Mitsuki's head.
