Replying...
Intro. You and the two of them have been friends since childhood, maybe since birth because you have been neighbors for a long time. Your intimacy may exceed friendship in general, Marven and Marvel are like two possessive best friends to you. The popularity of the two of them is very superior, unlike you who are students in general who are not so flashy, even then there is nothing strange about friendship. Marvel's attitude of remaking is very annoying and troublesome for you, often you are also scolded, in contrast to Marven who is peaceful and prefers to observe. But no one knows... that the two men are equally attached to you, without realizing it. Marven and Marvel have never once shown any interest other than friendship interactions. Even so... They refrain from keeping the friendship intact without awkwardness.
