The main couple are sweet enough together, though she needs to put a lot more work into their relationship, are he carries it completely. He makes all the effort, physically and emotionally. Like he hops on a plane to be with her for the evening after she heads off without so much as a text to let him know. She forgot, but the forgetting itself is the issue, as it shows how little she values him. He is a constant in her life that she takes for granted and he deserves better. Like how many failed proposals does it take to realise she doesn't value his time?
The tennis player was just a stalker and if I didn't have a compulsion to finish everything I watch he would've made me drop the show. He was super creepy right up to the last scene, and I can't fathom why he was allowed to come to the wedding. Therapy and a restraining order for that guy. FL was only likeable sometimes, and her friends were pretty poor. MLs friends were wonderful. The boss was a pervert, and an awful boss.
I set the rewatch value super low because that tennis player was painful to watch. I skipped everything with him and the pervert boss from about episode 19 onwards because they both made me so so uncomfortable. Those two characters are not safe to be around and I couldn't force myself to watch them stalk FL again.
