Yeah, I'm willing to place a safe bet that blondie and ikemen are fucked up in some way OR Sakura joins their agency and she starts fucking up so blondie or ikemen scold her because she never had this problem before, it would be funny if some new director got their hands on Sakura and ikemn couldn't protect her.
If it goes the way I think it will go, Shinobu will be depressed for a bit, Fumi will try to comfort him and they'll have sex but Shinobu just can't forget about Sakura, so Fumi seeks Sakura her spills the truth but then ikemen or some other guy fucks her whilst Sakura goes crying back to Shinobu.
An hidden fact within the series is that both blonde bitch and Yuma, both genuinely believe Sakura is really good actress tied down by Shinobu and it's implied both wanted to break them apart because they think Shinobu was holding back her talent
When the reality is another whole thing.
Sakura is a mid actress with an average body but Shinobu was able to take that mid girl and turned her from shit to gold by sheer determination and hard work.
Now both blonde bitch and Yuma took that away from Sakura
Congratulations you fucked it up!!! 🎉
Now if the author still cares about the theme of the series we'll get to see how much Sakura's performance tanks during the recordings.
That will hit Sakura because she'll try to cope that it's the break up that it's getting her out of focus and then realize it was all because of Shinobu's assistance.
Meanwhile everyone will bash her for being mid.
Extra pain if it's shown that both blonde bitch and Yuma plotted it together and are fuck buddies and Sakura happens to hear them going at it as they talk shit of her acting skills.
