It's the scene at the temple where Paul kissed Sri on the cheek. This is the translated script of the scene. You can compare it later with the subbed version (I'm still doing timing atm)

Meanwhile, Sritrung is at the temple speaking to Uncle Tong. [Uncle Tong isn't in this scene in the lakorn, it's a different older man. He said that Uncle Tong got sick and is at the hospital]
"When I found out, I was so startled. So was it an electrical accident or it was set on fire on purpose?"
"On purpose, how can there be an electrical accident in the middle of a corn farm?"
Then, Paul's car is being parked.
"Who on earth could think of something this cruel?"
"I've been wishing everyday that their bad karma catches up to them"
"That man is here," Tong motions his head to the back of Sritrung. She follows his motion and sees Paul walking towards them. "Are you here to see Luangpor?"
"I'm here to see this lady," Paul tells Sritrung who has an unhappy look on her face while Tong laughs heartily. "Can I talk to you?" He asks Sritrung.
"I am speaking with Uncle Tong."
"Oh! I don't have anything else to talk about. Please enjoy your chat like the young people do these days."
"Thank you, Uncle."
Tong walks off while laughing.
"Let's find someplace quiet to talk," Sritrung pretends like she doesn't know what's going on causing Paul to pull on her arm, "Why do you always make me get physical?"
"Let go, I can walk by myself."
Sritrung shakes him off and takes a step foward. Paul shakes his head and follows her.
Sritrung brings Paul to the back of the temple. Paul looks around, beginning to get suspicious.
"Where are you going?"
"The graveyard."
Paul stops Sritrung.
"Who asked you to go there?"
"You said you wanted to find some place quiet to talk. So I thought that it should be a graveyard since it's quiet..." Sritrung doesn't get to finish her sentence before Paul pulls her close and kisses her. Sritrung is startled for a moment before pushing Paul off her. She raises her hand, about to slap him. "You pervert."
Paul catches her hand to stop her.
"Being with you brings out my perverse... I've tried being so patient too."
"I..."
"What are you going to do?" Sritrung is unable to do anything but starts crying. "Hey, hey. Don't use your tears as a threat. I won't fall for it. So are we going to the graveyard or not?"
Sritrung shakes her head while smiling with tears. Paul lets go of her arm, "Don't pull that move with me again," Sritrung opens her mouth, about to insult him.
"Don't you dare. It's pretty empty around here too. I have to tell you that I'm a bad guy. I'm no gentleman."
Sritrung walks off in a huff. Paul smiles as he follows her.

I guess I can understand why they cut out that small part with the fake(?) crying since it didn't add or take anything away. Paul still gets to say his "I'm no gentleman" line in the end.
