I don't know how to connect this piece with renai rubi and sabito yoru.
Someone help

Series goes like this (chronological order)
0. Aazami - past Yumi x Kan
1. Sabita Yoru Demo Koi Wa Sasayaku -Yumi meets Mayama and breaks up with Kan chan
2. Renai-rubi no Tadashii Furikata (ch3.1 - 3.5) - Kan meets Shuuna and turns uke
- Narrow (Place collection) - dj Kan x Shuuna smutty sidestory
3. Hadakeru Kaibutsu - continuation Kan x Shuuna (Shuuna's POV as far, timeline parallel to no.2 for ch1)
-------------
Personal opinion - best reading order 1, 0, 2, 3
(Btw this is from Top comment ) you can find it just under the chapters

So this two alpha are already in a physical relationship either feelings involved or not......? No not at all they fuckin hid it from Yuu, that means they didn't want him find out. The reason they decided to temper with Yuu's secondary gender was merely cuz they wanted him to attend the same school as them(cleary they didn't have romantic feelings more like admiration)
Its not that I am obsess with the cliche and steriotypical Alpha X Omega ship........There are other shit tons of Alpha X Alpha shipped mangas that I enjoy. The feeling that this 2 alpha are getting Yuu tangle up in their relationship pisses me off(╯°Д °)╯╧╧
That went smoothly I was expecting sth tragic!
