He looks back up, and starts speaking English.

"Shall I compare thee to a summer's day?
"Thou art more lovely and more temperate;
"rough winds do shake the darling buds of May,
"and summer's lease hath all too short a date.

"But thy resolve no wayward gust can sway,
"nor can it fade like blossoms in the sun.
"Thine aims endure, not bound to brief display,
"but held with steadiness till they be won.

"Thy wit is sharp, and yet it cuts with grace, 
"directed not by pride but purpose pure.
"Thy values, firm, no tempter may displace,
"thy truths stand tall, unflinching to endure.

"But I'm no master of the poet's art. 
"What have I left to give, except my heart?"

And now the blush is back in full force but he seems to be doing his best to hold Haru's gaze anyway.

"I - oh my god, when did you write that, that's - oh my god -" says Haru, blushing back furiously.

"I—did most of it last month but I was stuck on the last couplet and then I wanted to say it to you and I—came up with it now—before I came to pick you up—you're doing that smile you do that makes me want to kiss you—"

"I want a written copy and a kiss."

"O-okay." He reaches over and opens the glove compartment to get a piece of paper that has the poem in fancy, pretty script, except the handwriting of the last two lines is visibly worse. "I also have a printed copy..."

He does not seem to be going for the kiss though.

Haru pockets the poem. Raises an eyebrow expectantly. "Do I have to say please?"

"Whyyyyyyyy are you so attractive," he whines but then yes, kiss.

Haru's... incompetent at kissing again. "I don't know! I didn't know I was doing it till you told me!" he says.

Nope no talking more kissing he needs to teach his Haru how to kiss again, now with added understanding of what kinds of kissing he likes. 

That's insane. Seriously? You've never had anyone confess to you? Not ever?

Oh okay then more kissing - oh wow - No! I'm happy with how I look and am but as far as I was ever aware my audience was myself!

Maybe they were too intimidated by your coolness to confess. All the better for me, I get to be your first and only everything.

Kissing is amazing actually Haru is discovering ~

Haru, I love you more than life itself and want nothing more than to spend my time with you but right now we gotta make a choice between stopping time to kiss and missing our reservation. Or, I suppose, stopping kissing.

Haru sits back. "I got dressed up! I want to make our reservation! It just turns out I like kissing which is one thing to hear about and another to experience."

"Just you wait until I kiss your neck," he says with a smirk but he also draws back, pulls his seatbelt on, and starts driving.

"I am waiting. Hopefully having imagined it in advance doesn't make reality disappointing."

He laughs but doesn't reply.

"Am I dressed up enough, I don't go to fancy things very often."

"I'm the son of the CEO of Mitsubishi UFJ Financial Group, we could show up wearing burlap sacks and they'd be happy to have our patronage, but you look absolutely stunning."

"I didn't say do you find me attractive, I said am I dressed up enough - have I been to this place before -"

"Yeah. You were gonna break up with me inevitably after we saved Tokyo and I wanted you to experience it."

"I don't think I would've. Broken up with you."

Wow it's a good thing Yutaka seems to be a good enough driver to not let being startled affect his driving but he is definitely startled!

"...I can put off elaborating on that if if might cause you to crash into something?"
