airi skipped a lot of things during a month missing for shinobu and fumi. By the time he talked with ryusei, i had a notion that ryusei already know about fumi and shinobu maybe a thing, and if ryusei knows something surely chico would know. The dynamic between the 4 characters should be already established. Chico must be eager to know this fumi chan girl, and she must be already familiar speaking with her. So the thing fumi did during the shooting is illogical. Because by interacting with chico, will make fumi realise that she is wanted and needed by shinobu.
How shinobu being portrayed as a controlling and stiff guy by revising the script to his own opinion, within a month time frame fumi must be already able to speak her mind out to shinobu strengthening their bond when she saw him simping the script with her ex gift. Instead of confronting she just went silent, right. So, during that one month period suddenly chico and fumi interaction is being put in a differrent box without any dynamic between them ever happened.
All that happen in chapter 135 are just an awful plot device for airi to make shinobu fits her fetish of necessity suffering of the mc for the story ending. I wouldnt be surprise that the ending going to be like copy of karami zakari with thank you paste big on the last panel. Her ideals is to make her female characters to be free from any suffering no matter how guilty.
So im skeptical for the last chapter airi somehow has properly acknowledge shinobu, that he needs a decent ending for his part in the story. It is not the characters that is bad in this story. Airi writing is the one that is awfully bad with plenty of plot holes in excuse of plot creativity.
