I Don’t Want to Be Brothers with You (2022)

Two boys are being put to live together by a "crazy" male parent. The newcomer being falsely as "cousin" or "brother".. it's suppose to help the attitude of the other guy so that he improve in his scores/studies.
At first they don't like each other much.. later they become each other's most important person.

Both are very light bl series on the verge of bromance or maybe even the opposite.

Both Bromance dramas based on Brotherhood and caring for each other but Killer and healer is more eccentric than I don't want to be brothers with you

Both have good Bromance and brotherhood ,, both have teenagers trying to succeed in some sport and both have amazing friendships

Both are family dramas and both have adopted siblings Bromance or brotherhood
both are very realistic dramas not fantasy

Both have friendship and bromance ,, both have friends fighting then taking care of each other to help each other succeed but I don't want to be brothers with you is more to the family than sports
