A difficult time for the super spy

Twilight gets an extra mission for which another spy, Nightfall, will join him. They have to participate in a tennis tournament where there are no rules and everything is allowed. If they win this, they can choose an item of the private collection of the organizer, which is what the liaison is about. But Nightfall has a secret, huge crush on Twilight and might compromise the mission without realising it.
Twilight's "wife" is also getting jealous and this might compromise Twilight's main mission...

Not an easy time for the super spy!
