Wonderful writing and incredible plots. I could easily submerge in this game 'cause the writing is just so vivid.
Following things might include some spoilers:
Sanghoon's character is one of the most outstanding part of this game. Just like the ones stayed in closet in their teenage years, the blurry feelings of sexual orientation (By the way, the double meaning of this word is all over the text and when I found that out, it's just actually surprising and moving) and sexuality, the special emotions, the tangled mind against the old tradition, and also the jealousy, are really really impressive. The author's writing skill is still perfect. Simple word but delicate structure of the plot. The echo between the sex of Mia and and the sex with Marty just makes me fascinate.
Marty's character is also fun. He is just the one who was badly affected by the toxic masculinity of Bloodline frat party and he never realized. It just emphasizes that how harm of these patriarchal frarernity things could do harm to the guys in it. Yeah, he is not a real brother, and he can never be that, but after these years' unconscious effect, he just became a murder and made the twisted "brother" concept become his lifestyle. To be honest, he should be sympathized, 'cause he couldn't recognize who he really is in the end and became the worst version that Sanghoon could be. If he could open his mind to HJ from the start, would things change? I guess so.
Though what I thought is that Sanghoon would be more aggressive for the whole thing, the end that they rebel the frat party is still good. I always like to see people get rid of those traditions of toxic masculinity.
