4 stars for now, 5 stars if it continues being great. :)
UPDATE: After the third chapter, there's no doubt I would rate this 5 stars. It's so good. A bit of realism going on as well - something that I don't get to appreciate TOO often with yaoi. (But I know there are many realistic yaoi's that are more realistic than this, still, I really thought the straight man's realisation of "oh, he's a guy." between the relationship of a straight guy and a gay guy was very well portrayed in this manga.)
