Agreed, I think some of the people being butthurt in the comments aren't aware of how time may drastically affect the relationship depending on the circumstances.
I know this is fiction but it's a bit concerning to see people making a fuss over the ex who isn't being toxic at all to the MC. What MC needs is time in order to heal and move on and the ex has already went through that. Some relationships are never meant to be because of bad timing.
