I liked the character development between the characters. You saw Saifah and Zon who used to hate each other and ended up dating and getting comfortable with each other. In the multiple scenes where they could've kissed and didn't was done SO well. You saw how Zon didn't want to kiss and Saifah actually pulled him away and didn't force Zon to kiss him. Which I thought was done well because Saifah respected that Zon didn't want to kiss him and pulled away. Another thing is how you saw Zon getting comfortable around Saifah. After they were both gonna be in the music show thing you saw them develop the friendship even more. I also liked the fact of how you saw Saifah patiently waiting for Zon. He didn't immediately go after him. Most of the times were just him teasing Zon, he didn't exactly hit on Zon. (From what I saw)
Also, the thing about the novel. I found it uncomfortable how Zol wrote a fanfiction with her BROTHER in it. Like If I were Zon I would grab her laptop and delete that crap. Not make a promise with her! I just found it uncomfortable about how Zon's own sister would make a fanfiction of him and Saifah. They could've made a different approach in my opinion.
I can't wait for the special episodes of Saifah and Zon. Due to COVID 19 some scenes weren't filmed in time so they have to wait until this passes over.

For P'Fight and Tutor one thing I didn't like is how Fighter randomly kissed Tutor. You saw in the series how Fighter actually liked Tutor but, if he didn't like Tutor he would be leading him on and breaking his heart. But luckily Fighter liked Tutor and they became a couple. One bad thing is dad's drama. I don't think it would actually be done that quickly. The dad's drama just felt like a filler.
I also LOVE how they didn't use the stereotype where there are a soft weak bottom and a dominant top. If they didn't have those scenes I honestly wouldn't be able to tell whos top and whos bottom. That's one of the things I really love about these 2. Also from what I noticed they had a healthy relationship which was good.
Other than that Tutor and Fighter had really good chemistry and I love how Fighter took care of Tutor.

There are downsides to this series but other than that I really loved this series.
