Well, now we know Tanaka's given name isn't Yuuki. Too many listless Yukis in the manga world to begin with anyways
Eh, well, there's your friends and then there's your BF. The B stands for whatever you want it to be. Tanaka certainly doesn't need a motherly doting figure with Oota around
Rino, dear, don't worry, one of those girls sees Tanaka as a being beyond human and the other would rather die than be his GF. Being overprotective will just hurt you more
