expression
clash of minds; emotional conflict; discord
Describes a situation where people's feelings, opinions, or personalities collide, often in close relationships like friendship. The phrase emphasizes the emotional friction rather than a simple disagreement.
親友だからこそ、心のぶつかり合いを乗り越えられた。
Precisely because we are close friends, we were able to overcome our emotional clash.
あの二人はよく心のぶつかり合いをしているが、結局は仲がいい。
Those two often have emotional conflicts, but in the end they get along well.
Compound of 心 (こころ, 'heart, mind') + の (possessive particle) + ぶつかり合い (ぶつかりあい, 'clashing with each other'), from ぶつかる ('to collide') + 合う ('mutually'). The phrase literally means 'mutual collision of hearts'.
