Firstly, I love how the main leads are of two very different worlds and backgrounds, one is a singer who is a public figure and one is a top computer science student. I love it when drama have such leads as there are more and more such cases in real life that the drama can shed light on.

Secondly, the realistic part about an older woman dating a younger man which is slowly becoming more acceptable in our society. However, there is still some stigma towards this, more commonly the parental rejection and your friends thinking that younger man are not able to provide and protect you the same way an older man would, which I think also shed light on real life scenario.

Thirdly, the drama did teach us some very important life lessons:
1. If you truly love someone, you should give it a shot and not overthink about whether both of you are compatible or not. Afterall, it is better to have loved than to never love before. If it works out, that is great. If it is not, we should still thank the person for the experience and wish them all the best and to meet someone more suitable in the near future. - Between the main leads
2. If you truly love someone, even if the person does not reciprocate, respecting their choice and giving them the blessings is the most mature thing to do. - Between the female lead and her close friend who is always there for her
3. We cannot keep living in the past and not letting go of the past, this will only continue to affect and hurt us and also the new people who wants to be a part of our life. Letting go is hard but that is the only way one can start being themselves and living their life again. - Between the second main leads (The actor and comedian)
4. Being able to become mature and put behind your past misunderstandings to be there for one another and to become close friends again despite not talking to each other for a long time. That is how a true friendship should be. - Between the female lead and the second female lead (comedian)

This is certainly a really beautiful yet simple drama without much twist and backstabbling, just family members who are supportive of their relationship and a few close friends who will always be there for them.
