Honestly, I've never understood why Hiiragi, Shizu and Yuki never included Mafuyu in their band, even just to come and watch their practices. They all knew he liked music, especially Yuki but they just excluded him from their circle, which led to the issues between Mafuyu and Yuki. Now its happening again and they (Hiiragi, Shizu and Ue) should know better. Stopping repeating past mistakes and communicate.
I'm pretty sure Mafuyu excludes himself. He thinks he can't do it, so he turns away. He thinks he can't fit in and so he doesn't try. Yuki, Hiiragi, and Shizu accepted that about him and didn't push.
Uenoyama does push but not enough - he doesn't know how to get through to Mafuyu most of the time. He had to grab Mafuyu and scream at him way back at the beginning to get him to sing. But that's not really acceptable behavior, to yank and yell at your bf all the time. Besides, Hiiragi and Shizu were just telling him that Mafuyu needs time to think it through - so he's giving him that space.
They are wrong though - Mafuyu needs help. At least now he's willing to find that help. Kaji will help, hopefully.
Read the first three chapters (on Lezhin), and you all aren't ready.
Spoilers......
If you thought chapter one was HOT, just wait the entire next chapter is hotter. Its just what everyone has been thirsting for between these two.
In chapter three we get some backstory of Chiwoo and Kyujin in the early parts of their relationship. But then, HE (Jihyun) shows up at Chiwoo's place of work after hours with a bouquet of red roses and say "I've missed You" to Chiwoo. At the moment Kyujin calls Chiwoo who tells him not to come to the shop to pick him up and hurriedly ends the call. Kyujin feels all anxious. I think its just crazier from there on.
Read the most recent release and oh my, that was an unexpected turn.
