Japanese names

Hi

My husband and I have two beautiful girls (Kiyo and Hotaru) and when we named them, we gave them the middle names Aiko and Suki, both of which mean beloved.

Now we're having a boy, and we want to continue the pattern, and give him a middle name which means 'love' or something similar (loved, loving, beloved). Unfortunatly we havnt found many. Any suggestions? Thanks
