This one's pretty tame NTR-wise: the cuck never even confessed to his friend, why am I supposed to feel sad that she hooked up with somebody else? Oh well Terasu's art still pushes my buttons either way.
I have no idea if the Japanese title is right or not, I took it from the Korean version that was uploaded, if somebody knows better than please get it changed.
Also fuck Terasu and his transparent dialogue bubbles and chicken-scratch hand-written kanji. Also fuck me for realizing halfway through editing this that there's a version without the text and I could have just used that and made my own dialogue boxes, but I'm stubbornly pressed on instead of starting over.
