Somewhat reminds me of Needy Streamer Overload? Not really, after reading the rest. Vtuber is depressed, gets into ??? relationship with manager, gets better, now manager is acting all ??? because Mahiru is getting better. Gets jealous of bl fanservice etc.
Interesting display of emotions---bit complex. Nice smut. Enjoyment entirely depends on how they'll treat relationship from here on out.
