I would recommend this show as one of the must-watch. The storyline was refreshing, and the cast members were cute and did justice to their respective characters. There were minor put falls which showed how much the characters have matured. I have no words to express my sincere gratitude to the cast and the entire crew members for this extraordinary show.

Favourite scenes:
Gun and Tinn's confessions scenes near the pool,
The Tilly Birds's "Just Being Friendly" MV,
The Hot wave performance,
Gun and Tinn's cute small moments,
Tinn's mom standing up for her son in front of Decha,
The beach scenes,
The band's final moments in a music club,
Prom scenes were incredibly shot, and emotions were relatable.

Plot:
This plot is more related to the high school musical, which is one of my favourites. Basically, the story is the journey of Gun and his band to overcome hurdles to win the Hot Wave competition to bring back the glory of their music club and pay tribute to their seniors who lost at the Hot Wave, and how Tinn secretly helps Gun to win the competition without will go against his mom/principal know about.

Band members:
The band comprises Gun, Win, Por, Yo, and Phat, with their newest member Sound.
The band is very laid back, loves to eat bbq Pork and get into trouble, and has a poor reputation due to their academic performance.
Everything changed once Tinn became School President.
They had to overcome their fear about the future and their skill to move towards the competition.

Gemini and Fourth were the perfect Tinn and Gun, and I cannot imagine anyone else playing their characters. Tinn and Gun started as enemies because Tinn's mom is their principal who does not like music club, but Tinn secretly has feelings towards Gun. Throughout the series, Tinn finds a way to initially secretly help Gun with a music club to get close to Gun. Tinn's love for Gun is pure and selfless, and he always supports Gun's dreams. Eventually, Gun also develops feelings for Tinn. Gun and Tinn were cute together, and their chemistry was off the charts. Tinn was heavily whipped for Gun. When Gun had difficulty writing lyrics, Tinn's song nourished the motivation Gun needed. Gun and Tinn's kiss scenes were hot AF. Tinn and Gun are each other safe zone, and they want to share everything first before anyone else. Angry Gun is scary, but Tinn doesn't leave his side, which shows how much Tinn loves and cares about Gun. They came a long way.

Sound's entry brought the drama element to this series. The MV brought an unexpected development between Sound and Win. Win and Sound are hot-headed, but everything changes once they begin to develop feeling for each other.

Out of all the people, I did not expect Yo to have an online girlfriend (who thought Tinn was Yo). I felt terrible for Yo and Nook, initially when bandmates were against it, but finally, when the band was okay with it, there was another unexpected twist with Yak's re-entry. Eventually, Yo-Nook became one.

Tiw (Mark) was the best friend and wingman for Gun and Tinn. Because of Tiw's brilliant idea, Gun and Tinn became much closer. Tiw was the best friend Tinn could ever have. Tiw and Por were very cute, and their relationship quickly developed. I didn't see that coming.

Yak is a kind, devil, manipulative, supportive senior; who brought the best performance out of the band members for the Hot Wave.

Jorn is an annoying character who hates the music club, but he has a change of heart and supports Tinn and Gun's relationship.

I didn't expect Decha (teacher) to bad-mouth Gun and Tinn; he got what he truly deserved.

Parents:
Gim (Gun's mom) is a pure soul; who supports her son's dreams and pushes him to excel. I felt terrible for her, but everything turned out fine. Gun's mom trust and likes Tinn. Tinn's mom is against the music club and music in general. When the truth came out, she changed her perspective. Tinn's mom and dad's insecurities were usual, and every parent has these doubts, but Tinn's dad brought some sense to Tinn's mom. Gim (Gun's mom), Tinn's father, and Photjanee (Tinn's mother) were supportive parents who cared about their children before thinking about society.

OSTs:
The OSTs were fantastic. The band's and Gun's performances were lovely.
The Tilly Birds's "Just Being Friendly" MV was extraordinary and lovely. All the other OSTs by Fourth, Gemini, Ford, Winny, Satang, and Lookwa were excellent and had a comforting voices.

Hot wave:
Though the band didn't win the Hot Wave, they won the audience's hearts. Poor babies, they are blaming themselves and each other for the loss.

Questions I need to answer:
What happened between Sound and Tinn in the past? Why he hated Tinn initially?
Why did Tinn's mom hate the music club?
Why did the principal change in the first episode?

A perfect ending:
Gun's lovely interaction with Tinn's father and mom and the final kiss scene made the ending wholesome.
