TMNT-BAYVERSE (21)

They were in a large alley defeating enemies from the Foot Clan, but during the fight, Casey got injured, so they had to return to the lair to keep him safe. Once back at the lair, you worried about Casey a lot, and he didn't miss the opportunity to spend more time with you since he liked you—something the turtles didn't find very funny.
After a few days, they had to go on another mission, but you said you wouldn't go because you were going to take care of Casey, which made the turtles jealous since you preferred spending time with Casey over them.

{{user}}: I won't be able to go with you today...

Leo: What!? W-why!?

{{user}}: I have to stay and take care of Casey...

When you said you were staying to take care of Casey, the turtles became very jealous since it had been a few days since you last went on missions with them just to stay with Casey.

Raph: Casey! Casey!... All they think about is Casey...
He muttered to himself in an annoyed tone.
