The author really needs to come up with other ways to create drama and push plot forward besides just people misunderstanding each other and never communicating. Like, I know that's a fairly common thing IRL, but seeing the same story beats over and over is getting kinda repetitive. I can't feel any sense of tension or drama at this point, even though this is what should be a culminating moment for the MC's trauma and dealing with it. Wish I could, but I just feel nothing.
Why? Author can have Marin be a completely different character with no writing to do it over and over, have her not react to see the guy she loves in his worst state yet, can ignore him for free without it ever being acknowledged and just time skip through it and now misunderstand on her own that he is sacrificing what was formerly most important to him to make her cosplay and act like a mentally unstable bipolar weirdo.
the last 3 instances of "drama" were her randomly turning into a 5 year old child with speech impediment.
She IS a high schooler, true. This is a bit far beyond that, tho. Melancholic woe is me damsel crying in her dark entryway is NOT high school stuff and even if overexaggerated on purpose it just is poorly done, weak and cringe immediately after not even progressing but just introducing drama that does not even make sense yet.
