Also as newest Q&A goes from chapter 100 from the author confirmation.
Doona is bisexual
Haseol is heterosexual
Gyerin is lesbian
Minho is heterosexual
Wookyung is bisexual
Strange cause I remember reading in past Q&A that author considers all characters bisexual when it was still at Lezhin, maybe they changed their mind now.
yep! i was surprised too cause it seemed like she might be setting something up with gyerin and haesol? i hope since she confirmed gyerin is a lesbian not bi, that she gets the loving gf she deserves and her and haesol just become good friends. or maybe haesol will dress up in drag one day and when gyerin sees him she loses it for a few mins lol. at any rate this comic doesnt rly need More characters but there's no such thing as too much lady on lady lovin'

Only problem with recent chapters of Gyerin is that Gyerin is actually in love with Dona, but she gets shoot down. She also dreams about finding a hot dom women who would both love her exclusively and be a dom to her in bed sometimes.
We all know author will ruin her character and will bring her down fully to Dona plaything level in future when Gyerin will feel too lonely without Dona and suddenly her being into threesomes or drunk fucking Haseol or any other bullshit like that will be ok cause she's doing it out of loneliness (and in author mind seeing the Q&A being bisexual means there's no difference in loving a guy and a girl which is complete bullshit but hey it makes "writing" porn easier, it seems the author also really doesn't know what BDSM means seeing the story result).
That is the real problem with this story, it doesn't matter how funny and active Gyerin is, or Haseol, they all will get trashed to Dona level with time. It seems the main problem with this story is that loving Dona makes you mentally ill for her at the same time, becoming basically a sexual slave out of love for her.
I would gladly see Gyerin getting a hot new gf dom, like her and Haseol going to BDSM club chapter to find new dom gfs but all of us know author will never do that.
And I don't think author will change the approach, if anything it will become more extreme for all.
