Not sure if this fits ur description

Yes it does! I actually thought there was another webtoon that fitted the description but I think this is the only one
Take a look at this one https://www.mangago.zone/read-manga/the_use_of_a_necktie/ but I'm not so sure if the seme is shy
That's all I can think of (￣∇￣")
I'm looking for a BL webtoon where the seme has red hair, and I remember him being super shy and blushing whenever the uke did his thing. I even thought the seme was the uke at the beginning. Do you have any idea of which webtoon is it?
