She probably going to transfer to Mio's agency and probably Fuckboi will be mad about that sex scene and after that results in a breakup.
One person in the 133's forum said a thing that i found interesting,is that the fuckboi was the only one who did not appear in the last page.That could mean something?
The last panel said "AS THE NIGHT WEAR'S ON EACH OF THE THREE HARBORS THEIR OWN THOUGHTS ONLY TWO MORE CHAPTERS CUNTIL THE CONCLUSION!!!"
IMHO, the main characters for the last 2 chapters are Sakura, Shinobu and Fumi. Not fucboy anymore.
Sakura is on the decision to go back to be a gravure model to prove that this career should not be looked down. It means she must change her agency to be with Mio.
Fumi will not be an actress unless the director is Shinobu and now she's asking him directly "what do you think about me (in romantic way)?" because he still did not reply her confession.
Shinobu must decide whether he will use Fumi to become successful and how to reply to Fumi's feeling.
The author will use time skip to answer all questions above.
It can be Sakura x Shinobu or Fumi x Shinobu or all become single. I don't think fucboy will get any girl.
