It's good that the arc ended as fast as it did, but it also felt like a lackluster way to end it. It's fine what the author's trying to convey love through the manga, but being kinda karasuma's thing hamper's the so-called love of karasuma and fushimi.
And you can of course make the arguement that fushimi did help karasuma with the manga, but she basically was just a model for him? Sure that's something but, it's something more so specific to karasuma than fushimi
And even in fushimi did contribute something meaningful...I think it would've been nice to actually go in depth with the story they're writing rather than playing it off as some great display of love all of a sudden without understanding what the actual love is...
I will say however that the thing is set up properly and Shouiji and Karasuma's relationship of working on this manga makes it make sense why she'd enjoy it. It's just again rather than being told Karasuma expressed his feelings it'd hit deeper if Karasuma expressed his love in a way Shouiji can only understand or in a way catered to Shouiji.
By Doing that it'd help break up generic 'show me your love' aspect that every other manga has while connecting with the characters more and giving us the audience a plausible reason why she let go of her jealousy.
Ultimately, despite the harsh criticism I can give it a 5/10 maybe 6/10 as it's typical. It had setup and followed through, but didn't do anything extraordinary or even really different from the genre. Oh and fushimi was there...I guess...Extra points for Ojou-sama though.
Hope in the next part for more character development for fushimi next. She's a cardboard cutout who needs something beyond yuri and polyamory. (probably a good idea to lean more into her music obsession with help from karasuma so its more of an actual 3 way love triangle).
I can't say that this chapter isn't a step in the right direction compared to the horrible fushimi music concert so it's possible for this to improve later on.
