After reading the recent chapter of Q.A.H.I.T
I suddenly got this idea after queen and this woman whole thing ends you could write a chapter in which mina missed her sis/momo so much because it was her birthday (momo') that day and she loved spending time/birthday together with her(momo) so she was really sad that even jihoy couldn't talk to her and on the other side queen(chaeng) was planning to spend time with all of her wifes all together, so she told sana, tzuyu this and they were happy with it mostly sana because her could finally talk to her queen, but she didn't told mine about this cause she wanted to surprise her,so when she want to her place with sana and tzuyu she sees that jihoy was sitting in the chair frozen that she didn't even realize that queen was here, so queen asked her what happened,so jihoy told them why she was sitting here,whae queen knows the reason why mina was sad she quickly want inside the room with sana and tzuyu and when she sees mina at that site she froze at her spot,. while mina was so into her thoughts that she didn't even hear them,she was thinking about her memories with her sis/momo and she starts singing a song (still with you by jk) for her sis/momo and when she ends the song she was crying badly and the queen was feeling so bad that she couldn't even go to mina and than sans goes to mina and hugs her tightly, comforts her and that's where mina and sana's unbreakable friendship starts....
