This was an odd one-off. There was actually very little at all to differentiate the two male leads in their treatment of, or rather their attitude toward, the FL. BOTH assumed that she was theirs by right. The 2ML was more aggressively creepy and stalkerish, but the ML thought that it was perfectly OK to keep telling her "wait for me", for FIVE YEARS without telling her why she should wait. And then he apparently thought it was HER fault she left him. Ultimately, this was only romantic if you find patriarchal possessiveness appealing
