I'm interested in the consequences of, instead of "everyone" carrying out SENPAI, having a more efficient STB Matching System (Spin The Bottle). Sure, it could backfire: interested parties may fall victims of the universe's Random Number Generator, but it makes for some interesting Game Theory dynamics, which I call the Tinder Card Stack Dilemma. Any one party could be more willing to express interest in any of the other parties (assigned by STB), if they believe there is a low chance of them being matched with someone else they are more interested in. On the other hand, they could become more picky, and only express interest in parties they are very interested in, rejecting others because they believe there is a high chance of them being matched with greater interests. There is a definite trade off between efficiency and overall population happiness when choosing between STB and the solution described in the paper. Because STB is more efficient, it ends up being way more scale-able. But bigger populations greatly intensify the TCSD.
