It's this one sadly.
What's non con?
Non consensual
Are y'all referring to the sleeping scene? I too thought seme was forcing his way but then I read the translation and Yeomin actually was interacting with him. He looked that shocked because seme was giving him a BJ for the first time of his life (both their lives actually) and not because he was uncomfortable or disturbed. So translation made things less shitty but still seme did start touching Yeomin when he was asleep and drunk. I don't know what's freaking wrong with these authors honestly. Plot was going smoothly but no she had to add this stupid non con scene!
For the life of me I can't remember if this is this BL or another BL that I've read is gonna have non con in the future
