Jaanu comes from jaan — life.
Maanu comes from mann — the heart.
Dramatic, devoted, runs on jhappis. Checks on Maanu twice, always. Steals exactly one bite of whatever he's eating. Sulks facing away — and peeks over her shoulder within three seconds. Afraid of nearly everything, except thunderstorms. She loves those.
Calm, unbothered, secretly the more romantic one. Hides one snack somewhere, at all times. In every fight, he gives in by round three — maan jaata hai, every time. Falls asleep in five seconds, anywhere. And when nobody's watching… he practices dance moves.
Real otters hold hands while they sleep, so the current can't pull them apart. That's the whole story, really. Two small creatures, holding on.
