you can call saibara's to see him, or you can get the game harvest moon: more friends from mineral town. plug it in your ds's gameboy slot, then put in your harvest moon ds game inthe other slot. power it up, and every Thursday he'll come (go on Google and type in the search engine ushi no tane x6 - it tells you everything!!)
If you buy the Love Bangle from the Sprite Casino and talk to him, his affection points should show up on the bottom left side of the screen. Only if you talk to him in person though. He comes to the valley after you connect with FOMT or MFOMT.
At Gray's Shop
Personally, I think Gray, he is by far the easiest to get the affection of, and he's a cutie.

You can see Gray by using the phone in your house to call the Blacksmith shop when it is open. To actually meet him you will need a DS with a GBA Slot and a copy of Friends of Mineral Town or More Friends of Mineral Town. Insert your Mineral Town game into the GBA Slot of your DS and play Harvest Moon DS Cute like normal. Gray will visit every Thursday and on certain festivals.
