If he'd been watching her for awhile...enough that he knew she hung out with the Sempai MC...you'd think he'd be aware of her feelings for the latter. Guess you only see what you want to see...
@Sadisticmale I think it has something to do with "kawaii culture"...sweets are often cute. Ramen? Not so much.
@RobDog it comes from a prompt in a Call of Duty single-player campaign mission where you "pay your respects" to a deceased soldier by pressing a single button. The very concept of putting such a thing in a video game was so ridiculous as to ne farcical, and a screenshot from the PC version (where the F key is the "interact" or "use" button) displaying the "Press [F] to show your respects" prompt was widely circulated and mocked. Now folks on the 'net often "press F" to pay their respects to a "fallen" comrade, whether sincerely (like when a streamer dies in a game) or ironically (as in this case).
