So Jarunee did died in the end. As heartbreaking as I felt, her death were justified because she took the pills before she turned back to 15. (Also, if you notice, the series kinda hinted that because Jarunee was the only one to celebrate her 56th birthday among the leads, and the sign never flipped to 56). Poor Boom's character and her dad who loved her with all their heart. Her funeral scenes were well done, love to see her becoming an inspiration for the other characters to enjoy their lives to the fullest. I believed she had passed away peacefully because she was able to live the life where her happiness is treasured instead of dull rules she had to oblige to.
Paul, I think, was the most sympathetic character out of the cast. All he got was heartbreaks after heartbreaks. The love he had with Mathee was always unrequited, and as soon as he found a person that loved him dearly like Phiphu, he had to turn back to 55 and left that love forever buried. The best moment he got was when he confessed his feeling to Mathee and received a hug (I did think by that time Mathee knew that the 15-year-old standing before him was Paul). I know this is a super unpopular options among viewers of this series, but I think I know why the writers didnt let Paul and Phiphu get together. I will explain it at the end.
I didnt really tune in to Jaya's storyline but I can see her development as a character. From an arrogant, snobby and sassy diva, she turned into a more reasonable, hardworking and overall decent people. She learned to move on from her past popularity and became more considerate towards her friends and manager. She was the most dislikeable character in the first episodes, but by the end, I understood her struggles and valued her efforts. Glad she was able to live her dream as a singer once again.
Thep was the most realistic character, to me. Similar to Jaya, he started out as a cocky, overconfident and somewhat negligent towards his family. He knew his family depended on him to save the doujo but he wasn't too determined to save them. We all have that moment in our life. Then you have his moments of temptations with the younger girls which broke his son's heart. Luckily the writers decided not to drag on that matter for too long and made him realize how important how his family is to him. I am glad to see his wife always supporting him even when he was off the track. I also loved his confession to his son, where he said he didnt know how to be a father because he never had a real father, but he would try to do his best. The moments where he was excited to see his son got a lover, when his son joined his training are the most father thing I've seen, stereotypical but genuinely convincing. Kayavine delivered a stellar performance, especially between costars with different ages. Its good that despite many hardships, he still got his passion for boxing burning vigorously in his heart till the end.
San's storyline is probably the most touching. He was pushed to his downfall at the age of 55 because he was never understood by his parents. What he did was always considered rebellious and brought shame to the family. His dad never gave him a proper lecture and only belittled him for his mistakes. That's why he left his house to spite his dad, even though he knew that he would have to leave behind the woman of his heart. Had his family been more accepting and understood their son, San would never have been put in such predicament. Fortunately he was able to stay with his dad and made up with him on his deathbed. Also, he was able to actively fight for his love when he saw the apple of his eyes mistreated by her husband. Out of 5 characters, I thought he was the one to be most mature. Nanon is a great actor, he was really convicing when he expressed his character's love for Prim without making viewers awkward with their age gap.
Overall, I was wrong to say that this series had an upbeat feeling. Well, maybe I'm not as wrong. The series did have heartwarming and comedic moments, but as a whole, the ending was rather realistic, and that's what makes it sad no matter how you viewed it. Reality is always a bitter pill to swallow, and magic doesnt exist to rectify this situation. At the end, Jarunee still had to die, Paul still had to turn his back on Phiphu and Thep still lost the doujo. The 29 days living in their 15 selves may have been a good dream for them, but at the end, everyone will have to turn back to 55 and face their fate, with all their remaining problems. Whats different this time is what they would choose as their priority. Take Thep for example. At the end, although he still lost the doujo, he was no longer burdened by that fact because the most important thing to him then was his family, no longer the doujo. Paul is the same, he understood that true love is not possessive, and was willing to make sacrifices for his loved ones to be happy. Jarunee too. She was able to live the best of her lives and spent time with her loved ones until her last breaths.
