Ngl I feel like she probably does it to make Doha more mysterious since we know nothing about him, I’ve seen her previous work and u can definitely see how they are their feeling.
My problem here is Bada more than Doha, I think Doha is really into Bada.
I'm on the same page as you. Sometimes, I question whether Bada is just saying he likes Doha or if he actually likes him. I'm kinda confused about Bada's feelings before (/≧◇≦＼) but I think I believe it more now because Bada seems to want them to get out of the game together (๑•ㅂ•)و✧ i dont think he would mention it if he didnt mean it.
I don't mean to be rude but this author really sucks at expressing the characters feelings through drawing especially when the two main characters are intimate, you can't confirm exactly if they are sincere in what they say or are fooling each other to get through the game.
