So I guess in the past Arjuna defeated the Dragon King but then sth like lost himself? That's why the others had to stop him? Anw thanks for the chapter. This manga has really good art.
I pretty much think it would just end up with "She's my GF" and then "Oh okay sorry".
Actually he explicitly said "I smelled sth nice" so it can even become a 2 men talk about perfume, like "Dude ur GF's perfume smells too gud"
"Ikr" *shrug*
IIRC in the previous chapter, Mikado did ask Miyuki about sth like whether the Shinomiya started to move. So I think they somehow got together in the same boat?
