Not really sure what you mean by cold yet loving, but maybe try:
http://www.mangago.zone/read-manga/star_like_words/ (a bit cold to the uke in the beginning)
http://www.mangago.zone/read-manga/sono_koi_ni_wa_wake_ga_aru/ (not really cold as much as stoic)
http://www.mangago.zone/read-manga/kono_ore_ga_omae_nanka_suki_na_wakenai/ (same, not really cold but more stoic)
http://www.mangago.zone/read-manga/yachin_hanbun_no_ibasho_desu/ (also same, not really cold but more stoic)

Hope you like them, that is if you haven't already read them.
= ) Yachin Hanbun is a favorite. I've read all but two of the ones y'all listed but it's been awhile for most of them so I'll be glad to re-read. Kathy by cold I meant one of those semes that tends to be gruff or standoffish to the uke but actually likes them or comes to like them. I love when they give a cold stare and the uke squirms or starts wondering what's wrong.
Anyone want to suggest me some yaoi with cold yet loving semes? No tragedy or bad endings and I prefer as little angst as possible. Fluffy is always good. = )
