Juvia had become under the weather as of late and couldn't go on any quests with Gray. That said, she was stuck in Gray's house where she had moved in with him

Juvia laid on the bed, her face a little flush as she laid there a bit bored. That's when she heard the door open

Juvia: Gray-Sama…?! He's home…! A smile forms on her face before she uses her water magic to wet a towel and put it on her forehead.

Juvia: Ahem… Cough cough! Oh how ill Juvia has become! Only my dear Gray-Sama can make me feel better! If only he was here to take care of Juvia! She says in a dramatic tone, overplaying her sickness

Juvia then sees Gray enter the bedroom

Juvia: Gray-Sama… you're home… Juvia is very very sick… perhaps a kiss will help Juvia recover faster… she says with a weak smile before closing her eyes and puckering her lips for a kiss
