Make Him Swim, Scene 3
Tawat's flirtiness towards Chai continues in Scene 3. While Chai was talking to Lem, Tawat even though this was not mentioned directly in this scene, is secretly listening to them. He's completely aware of what's going on. He learned that Chai is not actually Lem's bf, and that he's there to tutor Lem. Tawat can sometimes be a very conniving person, he tries to extract as much information as he can from Chai. This is the reason why he asked Chai, how Lem is doing academically. Chai in this scene tried his best to explain to Lem what he just saw that happened in the previous scene. But it seems that Lem was actually disappointed with Chai. He expected Chai to be more perfect or close to what his coach had described Chai to be.
