It's a cheating story, so you know what what you'll get. But the complexity of mc's emotion when choosing between his boyfriend and the old flame is surprisingly realistic. I can relate of how confuse the mc was, considering how relentless the old flame was, not to mention their old relationship was abruptly ended because of circumstances.
But the ending feels so rushed. If mc and his boyfriend have a longer conversation about how mc has hurt him and how mc was pushed into an emotional turmoil by the agressiveness of the old flame, their coming back together will be more believable
