Sorry to be bumping into this topic, but while I'm certainly not against anyone who ships these two, isn't melodytchi canonically clueless about love in the anime? It probably wouldn't have worked out even if lovelitchi actually WAS crushing on her.
Especially considering certain episodes that showcased that she has no idea what romantic love even is. Like that valentine episode when they were trying to figure out who wrote that valentine letter to her, thinking it was from someone crushing on her. (And she had no idea what was even going on.) Not to mention, I honestly don't get why people try to use that episode as proof that the two are in love with each other when lovelitchi herself was helping the girls figure out who wrote that letter to melodytchi, only to then find out that it was the one she made.
There was also that one episode where this character (I believe his name is princetchi?) was falling in love with melodytchi and asking her to marry him, and she went along with it not even knowing what marriage meant, nor even knowing that he was crushing on her to begin with.
I'm indifferent to the ship itself so it doesn't matter to me whether people ship the two or not, obviously they can ship whoever they want and have fun with it, so if anyone ships these two, by all means continue on! Even though I'm indifferent to it, it is a pretty cute ship idea nonetheless.
