Posty♪ All I wanna do is fall in love with yooooou!
... *sigh* Oh, won't I ever find true love?
...I say! Hello there! I'm looking for
1 Sea Bream of Love!
If only I had one of those...my unlucky love Life might
really pick up!
In return, I'll give you a secret item I keep stashed
right here in the ol' mail slot!
Yep, my Treasure Chest! Oh, and 600 Dosh to
sweeten the deal. OK?

PostyThank you, friend! Now, remember, that's
1 Sea Bream of Love!
By the by, the name of the woman I love...begins with
the letter L.
And that's all I can tell you!
PostyOh... Well... I'm used to rejection. This is nothing.
PostyIs that... Is that...a Sea Bream of Love?!
Did you bring that for me?
[Choice: Hand over / Keep for now]
PostyAh! So pink! Such a pretty fishy! Pink...now that's
definitely a love color!
Here. Your reward, as promised! Please, take it!
PostyOK. If you don't want to be seen handing it over...
maybe just slip it in my mail slot!
PostyWith this li'l fishy, my love Life is gonna see a
huge improvement!
I wonder if SHE might even reply to my letters?
