This Toda guy doesn't seem to be a love rival. He looks to be a supporter who likes messing with them. Though from the looks of the latest raw (14), some new guy just appeared who could be an ex of hers or something.
@ApolloX1209 : If they put him in the back or something, then I wouldn't get to type menacing for the "ゴゴゴゴゴゴゴゴゴ" sound effect every time it shows up! (I will lose all meaning in life.) Although, realistically, it's mentioned that it's a small flower shop so to some extent avoiding customers completely is probably difficult?
Konoe is clearly the kind of character who’s voice and thoughts wouldn’t be nearly as obvious without constantly dragging out his last vowels with tildas. (~)
Maybe they will get yakuza customers in the future with a menacing dude like that working there. Also some random macho men who wouldn't want to enter a flower shop otherwise, but upon seeing the brute already there, they might change their mind.
