Doujin comic

This used to be on doujinland before it went down, alternatives to doujinland are also appreciated.

In this comic a guy who saves a puppy and gets hit by a bus and gets stuck in a time loop with a mysterious girl... also maybe classmate. They fuck a lot of times thanks to the time loop, and it's revealed that she has the power to create time loops. She had been watching him and knew he was secretly suicidal? So after enough fucking he's cured, the puppy is saved, he doesn't linger to get hit by the bus, and they probably keep fucking.

I might have misremembered the plot slightly but you get the idea. The art was really good, so if you know the name of the artist or anything about this comic, please let me know! I found it therapeutic...
