Sunao Ni Narenai Otokotachi

From Fantasyshrine:
Suzuki Masami has been painfully aware of his rival in high school swim team, Kashiwazaki Yuichi, ever since Kashiwazaki saved him from drowning. As fate would have it, now they both work in the same company! But unbeknownst to Kashiwazaki, Masami is behind the reason why Kashiwazaki never gets the worms (girls). Will Kashiwazaki realize who’s sabotaging his love life…? The gentleman-like, love story between two rivals.
Also included is a love story between a super-handsome foreigner and a chef with a phobia of foreigners (xenophobia).
