Should work.

Do you know what chapter this would be

I don't think that's a spoiler since it is shounen ai for a reason lmao. Its unlikely the author even thought about positions/roles.

Imagine whatever you like~

They did it but the side stories from the novel were not adapted into manhwa. The top is choi soobin(healteaser) and the bottom is sung chahyun(jja)

I kinda knew Chahyun was the uke and Soobin was the younger and puppy seme type. Maybe I've been reading too much BL that these things are becoming almost second nature.

Where can we read the novel if I may ask?

Read it from here! https://noveltranslate.com/novel/raising-a-newbie-and-changing-it-bl/
The translation is ehhhhh but it's still readable(sort of...)

The side stories were not translated so i read it from booktoki and used google translate

Oh thank you! Hope someone gets to translate the side stories but this is good enough
