Any recommendation for manga in which seme has been so in love with uke for ages n uke doesn't notice or uke is hard to fall in love with seme? Coz I see lots of manga with the plot- uke is the one who loves seme first n has to suffer a lot coz of seme! I got enough of those. Thanks in advance! !!!
