So instead of writing a comment I decided to write a Review so that you guys know why I liked it and some people didnt.
First of all I have read the second novel and I hated the novel, you know why loved the series and hated the novel because the series changed many things that made me unable to sleep for 3 days after reading the novel. Seriously If they made the novel into the series this review would be 1.5 ☆ (and the 1.5 would just be because of mewgulf).
Now how was it different...
■Characters
There wasnt Leo, Phu, Cirrus, Khui, Seo in the storyline (not sure about Dr. Khun -don't want to read THAT again)
Ill summarize the novel here to distinguish the differences:
In the novel Fiat is shit because he is a shit he didnt kiss Type because he wanted to awaken feelings but to create differences coz he saw Tharn in the parking lot. After which Tharn verbally abused Type called him sult, cheater and basically degraded him (according to translation)《so glad it was diluted 》. Then Type convinced Kalenga to seduce Fiat (he did a excellent job so good that Techno was so jealous and refused to talk to him) and bring him to a suite whereby Type, No, Kalenga and Fiat's friends surrounded a bound and blindfolded Fiat and made the atmosphere like that Fiat was going to be gangraped and recorded his confession so that he wont interfere again and left Fiat in the hands on his "friends" all of whom then had sex (raped?) Fiat and also recorded it so that Fiat can still maintain sexual relations with them through blackmail. 《Was so glad this got scraped 》also the one that took care of Type when he was sick and whom Fiat thought was Type's secret lover was Tar in the novel.

How the series did a better Job
-Basically the series removed all the parts that were contradictory to a persons character like Type and Tar were molested so making Fiat go through the same thing wouldn't be right . They also introduced secondary couples and Characters like Cirrus and Phu, Champ and Khun and Seo and Khui (I laughed so hard when a disclaimer showed up stating it wasn't a recommended behaviour when Khui was eavesdropping on Tharn and Type through a pipe). The series also highlighted the characters seven years by making them so lovey dovey plus I think the reason other characters didnt had a kiss scene because they had to complete with tharntype kisses ??.

Now the reason the story went the way it went because they followed the novels storyline, Tharn and Type the series actually follows the novels to the T for example the first season was so inline with the novel that when you read the novel those you who have hated Type will see the reason for his behaviour like why he agreed to sleep with Tharn or why he abused the katoeys and how he realised his feelings for Tharn (I'll spoil this one.... so in the novel after Tharn agreed to Types sex buddy agreement .. they had sex multiple times and after each times Tharn got up and did his job or went to sleep on his own bed instead of cuddling and spooning with Type all this made Type realised that he cant get what he needs from Tharn (love and attention) by just being his sex buddy coz by thenTharn was a large part of Type's life so when he went to that girl's room when they were about to kiss he was seeing Tharns face that's when he realised he cant do it).
So by revising the novel they came up with this story which is the better version.

Overall if a person who read the novel would love this series and the people who didnt like this series I urge you to read the novel
