Well for sure it isn't a 10 rated BL series, but it's not a 3. Truth being that for me, as long as Joong smiles a few times an episode I'm satisfied! Also if he raises his eyebrows' and goes shirtless once an episode that really can forgive a lot of script weakness.
Yes the "Hidden Agenda" was not hidden for very long nor was it hidden very well at all. Therefore, this is for sure a "B" BL series...similar to B Movie. All the other stuff was acceptable, music was kind of generic for me. (yeah minus Joong singing.) Story was generic. School stuff Generic. Family was uneventful.
Joong was a good cast for Joke but I can't say the same for Dunk as Zo. I'll leave it at that. NIta and the Grandmother were good female characters.
My only other cast issues is what happened to Pat? Pok and Jeng are fine but Louis as Pat is the next most interesting actor in the entire series. It's like he fell off of the screen. (Did I forget something)
The Finale could have had a more secondary character involvement and I didn't really get Zo or the the fathers moment of realization: "oh I'm being a wanker and I should stop!" Not done well at all!

Yes it's watchable and yes it had some good entertaining spots, but yes it's time for Joong and DunK to grow up. No more school series for them please!
