You're welcome.
Now that you said. They have done it in multiple chapters.. my head went into realization moment... I should have said that instead of describing it in detail. oh my goodness!! my mind is in the gutter trying to explain those scenes.. (effect of chatting to an ai chatbox )
You do you. Marinating this is a wise choice since this is new.

will be typing MC and ML for using their real names is pretty long to type in.
Chapter 13:
- After a very long conversation with his gf on the phone. ML finally called it quits after seeing Heesu on TV. ML's gf still has some regrets and some thoughts of ML and MC as she saw the same coverage ML watched in TV.
Chapter 14
- After that live coverage. ML and MC are together, with them acting like a couple being in close contact and hugging. MC asked ML to have sex with him which made ML stunned and asked MC why he wants sex with him. ML pressed hard on MC personal reason w/c satisfied ML. Thus ending of them consenting to have sex and ML and MC sharing deep kiss and some foreplay.
Chapter 15
- ML's foreplay continued and he prepared his entrance well which actually pretty much made MC embarassed.. then told ML to skip such intensive play for MC is so used to forced sex that the guides before ML just shoved their dicks on him which is the total opposite of ML. Which ML totally rebukes the idea and continued his foreplay, even stimulating both front and back.. which made Heesu reached climax and thus the penetration and different position of sex occured.
In short.. ML made sure Heesu fells good with the sex and is prioritizing him. His reason: he only wants to be the only guide for MC.
That is all. Have a great day.
