In the shopping mall where Seo-Eun went to buy a birthday gift for my boyfriend, with whom I had been dating for two years, I never expected to see him holding hands with another person, and to top it off, with his best friend. Shortly after, she finds herself running into her younger brother's friend while completely drunk.
Everything was going well until now. 'Are you okay, noona?' But why am I in his bed?? 'W-We slept together?!' 'No, we haven’t done anything yet...' 'Eh...?' 'Yesterday you said those things... it was better to do them sober...' Was it due to the naivete of my brother’s friend, who is young, handsome, and successful, that I let my guard down? Something seems very wrong. 'What are you talking about? Are we dating?!' 'Are you really going to get rid of me after I’ve eaten you, noona?' 'I-I gave you everything, my body, my heart, and my understanding, noona...' Why is he doing this to me when there’s a long line of girls chasing after him?!

Opinion of My Brother's Friend Has a Big One!
My Brother’s Friend Has a Big One! is a manhwa that has 15 chapters, it is simple, its plot is not complex at all and it is quick to read. It mainly starts with a betrayal but as the protagonist, despite being a virgin, doesn't plan on falling, at least not for her Ex with a small member. She accesses the request (or in this case, trick) of her younger brother’s best friend.
However, it was something she was looking for, as she was enchanted by the large size of that boy’s member. Nevertheless, she didn’t think about the consequences, her regret for eating a boy younger than her, a boy whom she has known since she was little, just to vent her sorrows. Now she has to deal with a handsome and younger boy, her ex's harassment, and her ex-friend's constant messages.
Honestly, this manhwa, its plot regarding betrayals and the explicit scenes without any censorship, make it seem more realistic... Although every girl would love for a handsome and well-endowed boy to be looking for her everywhere. It is a pleasant manhwa to read and if you like these types of stories, this would be a very good option to read.
