I'm a firm TadaKomi shipper... But, hey, Manbagi and Katai (even if I know the author are playing his "love" for Tadano as a joke, hey, the dude's pretty cool, it could be a good partner) are nice people too, and that's exactly why I hate harem or love triangle situation (well, one of the many reasons): someone will "win", the others will suffers....
