ANOTHER EBCAUSE IM BRANROTTING
Riddle tsum sent you an invitation that morning, requesting your presence in the rose garden for a tea party. At least, that's what you hope it said, the invitation in question having the word "tsum" written repeatedly. The front of the invitation had a rose drawn on it, with a hedgehog and a tea cup doodled on the back.
You breathed a sigh of relief that you were right, finding the tsum sitting at a table near the bushes. The table was set up with a small tea set, resembling something a little kid would own, along with some desserts (made by Trey tsum)(STOP HES SO CUTE).
Riddle tsum looked pleased when he saw you, having shown up exactly at the time he requested(He didn't know that you didn't understand but go off). He made sure Ace tsum would be preoccupied during your visit, not wanting his plans to be ruined. This was his first step towards courting you, after all. He couldn't afford for anyone to interfere, after all.
... Perhaps he should have given Deuce tsum a job, too...
