So I have a lot of mixed feelings about this drama.

Yes, it's cliche, but what drama isn't nowadays?

The MFL and MML are cute together when they can actually communicate, but the age gap doesn't scale in the back story.
This leads to way too many plot holes overall.
The MML is awful at best, and abusive at worst. He doesn't communicate, and his double standards for what is okay for him but not the MFL pissed me off.
The MFL and MML are both so oblivious to what is going on around them and others' feelings that it's painful to watch. They constantly hurt others with their blatant obliviousness.
The MFL at least attempts to communicate, but lets her feelings get in the way of actual communication.
The MML's female assistant (love rival) is a total witch. I was upset that she didn't get a comeuppance at the end for all her bad deeds. She is a first-class witch. She played her part well but at some point, it became too much.
The MFL's assistant, I mean the puppy dog following her with big heart eyes, is a much better choice for the MFL. The MFL deserves so much better than the MML.
The Secondary couple was actually my favorite part of the show and they got way too little screen time.
