   Summary

   There’s the Avengers… And Sentry.

   The newest addition to the team comes in the form of an indestructible superhuman with an ego as impressive as his golden vibranium suit.

   The team doesn’t get along with him.

   According to Walker, he’s not human at all.
   According to Alexei, he’s too serious.
   According to Bucky, he’s quieter.
   According to Ava, he’s too boring.

   But to the rest of the world, he is the perfect superhero everyone can rely on.

   Mister Perfect Yellow.

   Now, it’s Yelena’s turn to go on a joint mission with him as a part of Valentina’s mandatory assignment in helping integrate the new member to the team.

   Everyone wants to know…

   What does the leader of the Avengers think of the Sentry?

   —

   Sentry and Yelena are sent on a joint mission together. Bad first impressions, a young scientist in imminent danger, one shared bed and a secret identity later, the leader of the Avengers is at odds between love and hate.

   Which one wins?
