   Summary

   Spamton seems elusive with his feelings towards you, despite how much Tenna wants both of his partners to get along. While there's no ill will, there seems to be a lack of wanting to get too close - until Spamton seems curious enough to change that in a physical sense. Whether it's a one-time fling or more, you end up agreeing to try and catch a glimpse of the version of Spamton that only Tenna is privy to.
