Part 1 was good and has good pitential. instead of having the main couple and just 1or 2 side couples, there was at least 4 side couples. By Part 2 there was still too much unresolved with all the characters. They took too long to build the relationship between Kaitoon and Valen, the main Couple. They also shoud have ended the relationship between King and Pete alot sooner and done more to build the King/Ink relationship. They could do a spinoff with them.
From what they say in the description about the series Valen was born on Valentines Day, but has never known love, even from his parents. He is working in his Sister Nisa's restaurant and she seems to care about and straighten out his life. The only time they mention Valen's Birthday is in the final episode, while Valen is having a temper tantrum. I think Kaitoon and Valen have the potential to be a good couple, but Valen needs to go for counseling because of his temper and jealousy. Valen has a tendency to get a little violent when he is angry. They needed to spend less time on flashbacks to previous episodes and more time concentrating on character development.
