Here's a tag. (: http://www.mangago.zone/tag/tsundere%20seme/
my problem with the universal tag is that several mangago users are tag-happy and just click the most popular tag when they mark it :( thus, it's a bit of a mess.
it goes against my obsessive-compulsive nature but anyway i do collect my own seme and uke types.
my tsundere seme collection is here http://www.mangago.zone/people/tag/49344/tsundere+seme/
tsunderes mostly reject admitting in a violent manner...
also, check my awkward semes. your description matches them as well since they either they are asocial and clumsy in social interaction or the exceedingly stoic ones they have a hard time showing their love (and i find them cute) http://www.mangago.zone/people/tag/49344/awkward+seme/
Hi! I'm wondering if anyone can suggest some tsundere seme yaois? The kind where it's obvious that the seme loves the uke but doesn't outwardly say it. Ex. http://www.mangago.zone/read-manga/shitsuji_wa_oose_no_mama_ni/
