Another version of the smartphone story but, with a bad end huh?

Is it? Let's see, MC joins a chat group where one of the members shares himself having fun with his "toy" who turns to be Rin (MC's gf), MC is unable to do shit about it but keep watching the updates and at the end she sends by mistake lovely messages to MC that were mean for the other guy and she quickly deletes it though MC already saw and just keeps there doing nothing. End.
Tbh the only thing in common is that they use a phone.

The story may not be the same but this is definitely inspired by the success of the peeking at the girlfriend's phone one. The premise of discovering the girlfriend's infidelity through chat logs/videos is pretty much the same.

The one thing that the other story got better over this one was a sense of progression. Looks like the girl in this one had already been conquered and we didn't even get to see it. Would have been nice to see the process of her falling.

That's why I don't see any inspiration.
