I like how Riho tends to be really firm with her wota when they ask her dumb questions.
There was this one handshake account where this happened:
Wota: I'm thinking of switching my support to another girl. How do you feel about oshi-hen? (oshi-hen = changing your oshi/favorite/bias)
Riho: If you're not prepared to pick an oshi, don't. Only pick an oshi when you have the determination to stick to her.
Wota: ...oh...
I approved of this.
I never oshihen until my last oshi graduates (Ai), and in any case it took me 6 months after Ai graduated to be determined to oshi Riho for the rest of her MM career. And I never sway either
Other girls might get my attention, but my favorite never changes. That dedicated enough for you, RihoRiho?
