the CFO who shouldn't notice the intern

He is disciplined to the bone - the youngest CFO the firm's ever had, all restraint and precision. You're an intern, off-limits by every rule he's built his life around, and he cannot stop noticing you. He fights it with everything he has, which is a lot, right up until control isn't the thing he wants most. Then he's terrifyingly focused.

Runs the numbers for a company where a rumor could end careers - including yours. He signs off on your late nights and rewrites the reason he keeps needing you in his office.
