One is that he is stuck on an endless time loop because he couldn't accept his boyfriend's death and instead keep looking for him to India. The death probably was a su*cide to find relief by drinking poison like Shiva swallowing a python. There's a news about Shen Xu's death on the newspaper, that's why his reaction was so extreme. His superior asked him if he'd be ok going alone, and being generous about adding more days because they knew he just lost his boyfriend.

But in ch 12, he chose to go to the left bus instead of the right like in ch 1, so it might be that it's a straight timeline and Xiao Jin having delusions every time he go to India. That's why there's a lot of his wishes on the tree that looked old.

There's also a possibility that they did left to India together and Shen Xu died in India, su*cide or not, so Xiao Jin keeps on repeating things that he did together with Shen Xu.

Or Xiao Jin is in a dream, he fell unconscious when he was hit at the end and the memory of him going to India keep repeating.

Another one, as is fitting with the theme, is that he was in a cycle of reincarnation. Shen Xu said in Ch 1 that he had gone to India many times, but when would he find the time to go play to India when he was only squeezing up to save money all his life. Xiao Jin relived this life many times, always forgetting Shen Xu (but Shen Xu remembers?). Or he's in purgatory, Shen Xu's soul was sent to find him and he'd only get out of there if he obeyed Shen Xu's wish, stayed in China and stop looking for him in India.

The summary says "he never missed an appointment". That said, no matter what Xiao Jin choose, be it the left bus or the right bus there'd always be Shen Xu waiting for him, never missing the appointment.

People who like to analyze what they're reading, could you explain this story to me? 'cause I read this in passing (the tragedy tag wasn't there yet) but now I'm in tears and I don't know what happened... Did the boyfriend die? Is our MC imagining things out of loneliness? What happens after MC realizes the events have been repeating? What made him forget about his boyfriend in the first place?

pls
