Very interesting development... did not expect this gloomy Gojo to develop, im going to throw my two cents , i think there is a parallel between Gojo and Tokio, as grandpa said to Marin a couple of chapers ago, Gojo is one of those type of persons to get fixed trying to achive, talking about how he could get into 30, 40, 50, and eventually like him, into old age and still striving for more.
Tokio seems very alike, droping anime adaptations of his works, just because its not up to his standards, talking about how even he could not make something like that. That seems like how gojo may feel about this creation now.
Now we saw him, alone in his room, tons of ciggs smoken , being impacted by the cosplay of Maririn, its said that this is the most "haniel" anything been done besides his own drawings.
So. Gojo. Creating this such a great cosplay , even Tokio acknowledge this. Is hit with a very heavy feeling of guilt or maybe impostor syndrome. This is not made for him, he cannot imagine Marin being as perfect as he sees her, being with her.
This now seems like an inflexion point, a point where Gojo will either go and live like Tokio, until he is old and bitter. OR Maririn pushes him past this mentality , pushing him to recognize his very impresive talent as his own. Like Gramps said, Marin has to be there and tell Gojo just how good he is.
YAH , thats what i feel and think about this silly cosplay manga. im hopefull the Author will give us more , ill wait whatever it takes.
