One again, don't expect too much of this low-budget Thai BL set in Northern Thailand.
The show is full of the usual Thai BL clichés and the storyline is not that original. Many of the actors appeared in other low-budget BLs, so are somewhat familiar faces but the acting has not improved much since then.

Here are some highlights and some low-lights:

The good:
1. The setting. I always appreciate BL stories that are not set in the usual big city like Bangkok and go out to explore one of the many regional settings that are available in Thailand like in this case when the main characters are from the Isan region.
2. The characters. There are 3 BL couples in this series but IG-Ruk takes the center spot, we know it, they know it. This is not like a GMMTV BL series with 2 or more couples with the secondary couples taking some time on-screen that prevents us from seeing the main couple and that is ok. True, I wished we could have seen a bit more backstory between Nakrob and Grateen, especially when we know Grateen is adopted because his parents were killed in a car accident. But, the interactions between IG and Ruk are ok. The side characters have their funny moments, especially Garto (playing Kaengsom) who gets a smack on the back of his head in nearly every episode. Garto is scheduled to appear in another BL show, "The Tuxedo", as a support character, so hopefully we get to see him in other situations aside from being hit by the other characters.

The not so-good:
1. The acting. Virgo (playing IG), Ohm (playing Nakrob), Pitchy (playing Thunwa), Fam (playing Mes) and a few others actors, have appeared in other BLs such as "Love Poison", "Love Poison 2" and "Love at 7-11" but given the budget constraints, I'm sure they don't get the luxury of having many acting workshops like GMMTV or Nadao productions have, and they might not even have an acting coach with them 100% of the time on set. So, some of the acting is not done very well with some dramatic scenes not conveying the right emotions.
2. The storyline. It seems the director/writer just ran out of ideas by episode 8 because from that episode until the end they fill a lot of time with songs. The show almost turns into a musical because on every episode there are at least 2 songs being sung by one of the characters. In some cases, the song does match with what the characters are going through, but they take forever and don't provide much since we can clearly see all are just doing a very bad lip-sync.
3. The never-ending clichés. If there is something Thai BLs have taught us is that they always bring some sort of cliché to their storyline. "Siew Sum Noi" is no exception to this. We have the jealous girl that likes Ruk and ends up showing pictures to Ruk's father. We have Ruk and Nakrob's father who first acts like the usual father who rejects his son being gay (he discovers Nakrob and Grateen in bed and sees the picture of IG and Ruk kissing on social media), he becomes violent and beats Nakrob and Grateen, he then chats with Grateen's grandmother and suddenly he changes his mind and begins to accept their relationship as if nothing really happens (and this all happens between the middle of episode 8 until episode 10). We also have the love rival as Thunwa declares his love for Ruk. And, we also have the typical arguments between lovers when Ruk and IG break up and get back together after a series of misunderstandings and miscommunication.

In the end, a mild BL series that was somewhat entertaining but did not provide much in terms of originality. Watch once and then come back to it after some time and when you don't have nothing more interesting to watch.
