I search a BL...

Okay so I search a yaoi where the Seme and a rather plain Uke both work together in the same office company. The female coworkers ask the seme if he could tell the Uke that they can all see his nipples through his shirt (or something) because they're all so uncomfortable with him not noticing...
He goes buying a undershirt / or he gives him a undershirt and the seme starts finding the uke cute etc.
It was short and already finished I think??
Thanks for the help y___y
