Uhm, I guess Inori wanted Senou to be more assertive (or rather possessive?) in expressing his wishes. Senou's lack of self-confidence always leads to "as long as you're there" or "it's enough if you're happy" which can be pretty frustrating. Inori was probably aiming for a straight-forward response (like Spongebob "I. NEED. IT.")
:)))) good one
