I remember the manga having a love triangle and one of the two characters who were dating or something developed feelings for another person. And the other in the relationship knows that about his feelings. And in the end it was revealed that he was turning back time to try to stop the other from developing feelings for someone else. Sorry if it’s confusing
Please help me remember the manga I’ve read not too long ago. I forgot if it was a straight or BL manga but the MC might have been a boy who has lots of half siblings because of his father? And he lives with his older sister and younger siblings. And there was a chapter where his house crumbles to the ground. Sorry I totally forgot the plot but just remember this.

I’m pretty sure it’s a korean manhwa or webtoon. I think it’s a friends to lovers. I completely forgot most of the story but there was a chapter where the bottom thinks the top is cheating and chases him and jumps on him from some stairs I think.
This maybe?
