Can someone explain the joke to me? I haven’t played enough blue archive to get the NTR reference
Late reply but uh, essentially Noa is Yuuka's best friend, but she's also implied to have quite the crush on Sensei, and Yuuka herself is commonly depicted as being "gomen'd" or cucked/AKA NTR AKA cuckquean for women, by other girls when it comes to sensei. Noa is chief amongst these girls who would "gomen" Sensei from Yuuka.
