THAT SEME SHOULD HAVE REALIZED IT ALREADY. He saw the mark and he had sex with the uke anyway. And obviously the sex was a success (as in the seme was able to insert his d into the uke and so on) which would have been impossible to be done between an uke with a mark and another seme who didn't create the mark. Yet they had sex anyway. If the seme use his brain to think a bit more, he should have realized that the one who marked the uke was him all along. Come realize it already pls and have a happy life together!
I feel bad for both of them. Poor seme is given a false hope and being used by the uke to get rid of his trauma. However on the other side, poor uke for being so frustrated and never really able to get over with his dark past to the point that he had to use the seme's affection.. I just hope they can communicate well and work things out between them after this..
This is the best tangled tongues drawing I've ever seen http://www.mangago.zone/read-manga/i_m_no_match_for_him/uu/i_m_no_match_for_him-chapter-13/4/
I see shallow plot and a whole lot more of sex scenes instead and I'm not complaining at all XD
