Don't listen to MincefireStorm. There are at least 2 love triangles. A SML likes and pursues the FL, and a SFL likes the ML. She's a childhood friend of the ML, but she comes later in the show after the leads have established their relationship.
Of course there's a love triangle. Did you forget the ML's friend with feelings for his wife pursuing her for around 5 or 6 episodes? And then there's the ML's childhood friend that likes him. Why are you lying?
