"Sure!" Giotto replied with delight. "What is it?"
Tsuna motioned with his fingers and Giotto bend down until he's the same level as Tsuna. Tsuna leaned in his ears and whispered, "I love nii-san the most!"
Giotto smiled and said, "Can I tell you my secret then?"
Tsuna nodded eagerly, "Yes!"
Giotto whispered, "I love Tsuna the most too!"
