"Suisei's Christmas party" is actually just a honeytrap for Miko and this anon unironically accidentally found it out
>>15326584 .
This scheme has been in the working for a while now, starting with Suisei "accidentally" mentioning wanting to do a hotpot party with Shiraken.
Suisei enlisted the help of all her friends, Noel will be throwing some party with the other Holomem to normalize the idea of "having a party with friends". After this, Flare was tasked with constantly bringing up the idea of a "Shiraken hotpot party" in her streams, planting a seed of "Shiraken party" into Miko's brain until Christmas.
Christmas is the most important phase of the operation, Suisei will now have to bring up the idea of having a Christmas party at her place and the other Holomem will have to give Miko so many thumbnails request that she will have to be late for this suppose "party". To make it more believable, Suisei also asked her friends to tweet some words regarding the "party" to make Miko, who is still busy with dance lessons and thumbnails making and who is a real introvert, to feel missing out enough and just decided to go there anyway despite being late. It's all over the moment Miko rang Suisei's bell, the honey trapping is complete, there is no party, there is no other Holo, there are only Miko and Suisei in that apartment. To rub it in more, Suisei probably took Miko's phone and retweeted a fan art of them then unretweeted it to sow more confusion on the fan and to put more pressure on Miko, hence

Suisei always gets what she wanted.
