If I did it:

If I were to include Christopher's date with Honoka, what would they have said to each other?:

"I'm going to take this chance to say what I should have told you when your parents invited you to move to Paris with them and you asked for my advice.  'Don't go.  More than your parents, more than anyone in the world, I love you, I want you, I need you by my side.  Stay with me forever."  I finally had a chance to make my feelings clear, now that we were the only two people in a billion miles.

"Even though you were super gay for my childhood friend Fuji-P and not me?"  Honoka cocked one of her eyebrows doubtfully.

"Fuji-P is a great guy, don't get me wrong.  But you know how Eden frowns upon same-sex relationships, so I had to give him up."  I played along with her, given that I was stuck with her memory of events, since Cute and I were the people who gave those memories to her.

"And there I was as a perfect rebound?"  Honoka looked less than satisfied.

"Is it possible to rebound off an ant into the sun?"  I replied.  "I mean, seriously, my feelings for him, and my feelings for you, was there ever any comparison?"

"You sure acted like he mattered."  Honoka replied.

"I never cried while calling out his name again and again because I didn't want to fight him anymore."  I said.

"That was me!"  Honoka didn't let me get away with yet another memory manipulation.  "After I proved once and for all I was the better fighter by putting you in a joint lock, I might add."

"You were the better everything."  I admitted with a smile.  "The better looker, the better dresser, smarter, kinder, more popular, more composed, the better skier, the better skater. . ."

"Oh I don't know.  There were things I admired about you too."  Honoka smiled, taking my hand into hers, where it always eventually went.  "You did win the middle school lacrosse championship, after all.  And every time it looked like it was time to give in to the darkness, you were the first to stand back up against it."

"I knew you loved me when you chose to stay."  My eyes radiated with joy from the knowledge.  "But I'm still sorry I didn't make it easy for you.  I should have done so much more to nurture that love, but I made you struggle with it alone all this time.  No longer.  From here on, I'll love you with the strength of a thousand suns.  Am I still in time?"

"Yes, you're still in time.  Despite already knowing my answer and embarrassing me by making me say it out loud."  Honoka squeezed my hand playfully with hers, like we always had, and always would.
