单身、异性缘欠奉的地产代理田一雄(吕爵安 饰)，某日意外发现上司翟国强(KK) (黄德斌 饰)的手机里竟存有大量偷拍他的相片。眼见秘密败露，KK 只好直接向阿田告白，更向结婚廿载的妻子 Francesca (简慕华 饰) 提出离婚。另一方面，阿田的姊姊因怀孕而离家养胎，刚巧新同事凌少牧(卢瀚霆 饰)正在寻觅住处，于是便搬到阿田家与他成为室友。当阿田苦恼该如何应对 KK 时，阿牧原来也一直暗恋阿田，并大方认爱，更与 KK 展开了激烈的芳心争夺战，令阿田平静的生活发生了翻天覆地的改变。阿田经青梅竹马梓芊 (徐㴓乔 饰)的指点，理解自己对 KK 的只是下属对上司的崇拜之情，因此打算拒绝 KK 的心意。与此同时，阿田发觉即使内心抗拒与男生交往，但对善解人意、无微不至的阿牧也悄悄地住动了心。面对突如其来的 「桃花运」，阿田会如何决择?
阿田回想起KK表白一事，不知如何面对。室友阿牧发现阿田心神恍惚，欲问过究竟，但阿田不想节外生枝，因此对之隐瞒。 本来正与太太渡假的KK，得知阿田搞错展销会的细节，决定取消余下行程回来救亡。 展锁会当日，众人各司其职。突然，KK面前有棚架倒塌，阿田二话不说冲前舍身拯救。被压倒受伤送院。KK担心得哭成泪人。阿田见状，竟然忍不住紧抱KK安慰，同时一切亦被阿牧看在眼里。 阿田回到家中，阿牧趁着阿田淋浴时，无意间发现KK在工作文件上留给阿田的细心评价，按奈不住的闯进浴室向阿田表白，并强吻阿田，吓得他六神无主。
被KK表白；被阿牧强吻；令田感到迷网。 阿田向Darren主任诉苦，告之有「朋友」被同性亲了一下，对话被Carman听见，更当场揭穿「朋友」就是他自己。 回到家中，阿牧解释前一晚的亲吻，只是男人间的恶作剧，阿田释怀，表示自己无法接受男男亲吻；阿牧听后心情复杂，更发现了KK约阿田午饭的讯息… 翌日，KK带同爱心便当与阿田「午餐约会」，并告诉阿田会尽快与Francesca离婚。阿牧不请自来，叫KK不要再纠缠阿田，更乘机表白。二人为阿田大吵，势成水火，展开了激烈的阿田争夺战。 当晚，阿田在Wonderful餐厅偶遇阿牧，田指责牧为了接近自己，而大献殷勤，把阿牧气得夺门而出，梓芊大骂阿田自私。阿田四处寻找，终找到阿牧，并说出自己很需要他。
Francesca怀疑KK的第三者叫「Tina」，于是装作委托阿田找新居，实情是查探「Tina」身份。Francesca见阿田忠厚老实，终向阿田说明来意，要求阿田替她监视KK，并找出第三者，使阿田进退两难。 公司众人来到Wonderful餐厅晚餐，得悉阿田正与阿牧同居，啧啧称奇。接着数日，阿牧被Darren为难，阿田欲帮牧解围不果，反被Darren教训。 另一方面，Francesca不断逼问KK离婚原因，KK却有口难言。 阿田不断被Francesca讯息轰炸，决定偷拍KK的日程交差。行动中，却被KK撞破，使KK以为阿田亦对自己感兴趣，令两人误会加深，KK更进一步邀请阿田共晋晚餐。 Francesca发现KK约了第三者晚餐，要求阿田里应外合。阿田左右为难，心知不妙，但又不能揭穿自己就是「Tina」的身份，只好答应赴会⋯⋯
