Lost yaoi

Hey! I want to find a yaoi I've read before. Actually, it might be more shonen ai but I'm not too sure... Anyway, it was between 2 men who were salarymen and colleagues. Bottom is "big" (like "fat" though I don't like to use this word) and has glasses, black hair. Top is the cliché of mr perfect guy, he's handsome good at his job etc... Top is the one in love with bottom. He tries to seduce him with little things like giving him little toys (maybe penguins? not sure), always being nice etc but it doesn't really work, bottom thinks he wants to show off he's the best or something lol. I remember top offers food to bottom often, bottom likes to eat. After some time, bottom start to think about the possibility of top being interested in him but I have to admit I don't remember if they finally go out, not even if this manga is completed...
Anyway it was cute and funny. Does someone know this yaoi?
