I found it better than HIStory 2: Crossing the line. The plot was nice. Along with the kid, 3 of them looked really cute togather. Inspite of the age difference, the MLs had a good chemistry. The Professor was really hot!! XD
Some issues like - being bullied because of being gay, being a divorced guy with a kid...these were dealt with preety well. But, the teacher- student relationship, how they could be affectionate even inside the college campus, and the gossip of students and other social issues were kind of ignored. Even though they did say they didn't care, I think it's kinda unrealistic. But then, the whole point of the drama was to encourage self-happines and prioritising oneself rather than caring about the society. So I guess that's okay. Even though IRL, things will be lot more hard to endure but definitely with a strong will and love, people can get through everything.
At the point where the ex-wife came in to beg her ex-husband's bf to let go of him...I seriously stopped watching. I was like- please don't let this be one of those plots where one of the MLs leaves the partner for the sake of his family and eventually realises they can't live without each other and gets back together. But, Thank God it wasn't! He firmly denied her. That's when I was happy and continued to watch the drama. Overall it's good. A cute, feel good drama.
