i am looking this type of manhwa where the mc uke broke up with his bf. but years or months(?) later.... The ex-bf comes back but in a relationship with the mc's sister. but after meeting again it seems the ex-bf still in love with the mc uke, and yet the sister seems kinda sus.
its a colored manhwa. chinese manga i guess?
