sorry but following
wait what
Perhaps you could be looking for The Royal Servant?
He doesn't fall in love but rather freaks the fuck out, read this one if you haven't, it's so funny!

THANK YOU!
SURREEE
No, but I have started reading it and I love it!
I read a manga about two different couples, I remember about one guy went to get his hair cut (the uke) and the guy that cut his hair (the seme) fell in love when he was able to see the uke's eyes. Later, they had the sex. :3
If anyone knows the title or a link to it, please reply. Thanks!!! >w<
