Yuuma is referring to the fact that he just took Hinata's virginity because of the fact that Hinata was commenting that now that he (Hinata) has experience, Yuuma could "finally ask [him] for help" - in other words, what good would it do for Yuuma to ask Hinata for help with relationships when it was Yuuma who took Hinata's virginity. (I have no idea if Yuuma was also a virgin before that point as well - I think I kind of imagine him not to be; just that he wasn't serious about any of the girls he had gone out with before…)
BTW, did anyone else think it was incredibly stupid that Hinata wanted a girlfriend so he could help Yuuma out, and then he went straight to him for advice?!? ╮( ̄▽ ̄)╭
This is a cute story and I enjoyed reading it!! There is one thing I was wondering about on page 34 there was a quote by Yuuma that says "Who was the one who took the other's virginity not to long ago", Is he talking about him or other peoples virginity he took? If it is the other people it shows Yuuma isn't a virgin ha ha ha!!! I would love to see more of these two!!! thx D
