Destiny Seeker

destiny seeker very similar to like BBS .
In DS instead of faculty rivalry its dorm rivalry with more couples and skinship.
also sometimes they pretend not to like each other because of friends and family .
one difference is BBS also has GL couple.

This is my first time doing a recommendation so I´m sorry if it´s not complete.

These two are similar because:
-both are BL
-both have the development of the story in the university
-the male "lead" is already in love with the other one

The stories are similar but destiny Seeker has much more skinship than the Nitiman so if you like spicy and skinship moments Nitiman is not for you.
I hope i could help somehow. :)

The series are similar in many ways. It tells the story of male leads who are enemies on both sides and later turn into lovers. Also, in both series, their love progresses in a very healthy way and you can see that they are more mature than their years. Both are very good, I recommend them.
