Okay so first of all, common reason why the ratings are so low because most of them are rooting for Sun Ho, I understand your frustration but obviously Hye Yeong deserves it too and I'm so happy that he is the one Kim Jojo choose.

STORY

The unique thing about this drama is the Love Alarm concept, which were the reason why viewers are so into it in the first place. I really love how they manage to pull off the flow of the story and how they connected "The Ringing World" by Jojo to the app itself. The love alarm app is too cute but not really commendable to function in real life cause it's dangerous and manipulative to people feelings. Aside from the love alarm app, most stories are cliche. I really love the ending, looking back at season 1, all of my questions has finally been answered in this season.

ACTING

Kim So Hyun always slaying her role, actually she is my favorite Korean actress and no doubt that the role of Kim Jojo perfectly fits her.

Jung Ga Ram also captivates my attention because of his expressive facial expression. I love him and the way he delivers the character of Hye Yeong is excellent. Then Song Kang acting is good too.

Go Min Si, compare to the first season, her character here is kinda cute. I was really irritated to her on the first season but luckily the character development helps the shows to became light and take a rest from the love triangle drama.

CINEMATOGRAPHY

As expected for a Korean series, they never fails to amaze me on how beautiful they creates shots and produce films.

MUSIC

This season was full of English songs and I love it. The music gives more emotion and impact to the story and it is a well suited one so I really enjoyed listening to it while watching the show.

REASONS WHY HYE YEONG IS THE ONE DESERVES SO MUCH LOVE:
(Since S1 EP1, I am a proud Team Hye Yeong)

1. He has the characteristics to be a role model at such a young age. Although he was born from a poor family without a father, it didn't let this situation to be his flaws. Appeal to Pity doesn't found on him and that's why I like how they started the story with Hye Yeong working and studying at the same time. Such a hard-working man since then.
2. He is the first one to notice Jojo. But then Sun Ho appears on the scene and fall in love with the same girl, at the ending at some point I feel sad about Sun Oh and it shows that the love triangle in the drama is effective.
3. He is a man of words.
4. Caring, kind, and lovely.
5. Willing to wait for the one he love.
6. He is soooo cute!!

I'm late watching this because I was bored after the poor feedback from the show but thankfully I still watched this. To be honest, it was a good drama and I don't think that it deserves a poor rating from the people who only came here for romance. Like just look on how they tells the past of Kim Jojo and how it traumatize her, she overcome it in the end by accepting her own and stating to herself that she is worthy to be alive. There are too many lessons in the show too but yeah since it is a romance drama people are expecting to let their bet lead to be the end game for Jojo but since majority of them is team Sun Ho, the disappointments affects the ratings.

Lesson I learned from Love Alarm 2:

"Liking someone isn't something to be sorry for, and expressing yourself sincerely is the best thing you can do for yourself and others."

PS: It's really hard to tell someone that you like him/her and even though the world rules with Love Alarm, I didn't want to install it.
