Help finding manga

So this has been killing me but... i just need to know the name of this manga. It's been haunting me for days. So, from what I remember, the seme is this black-haired very protective person. He even watches (or listens to, I can't remember) the uke from the uke's phone. The uke is super oblivious and doesn't know that the seme does that. The uke has wavy blond(?) hair. The uke also doesn't like to eat his vegetables or something, and the seme always makes a bento for the uke. Thanks a mil!
