것만으로도
This pattern means 'simply by ...' or 'just the fact that ... is enough to ...'. It is useful when you want to emphasize that very little is needed for a result. In the story, it highlights the idea that emotional closeness can happen without many words. Example: 가만히 들어주는 것만으로도 친구는 안심했다. = Simply listening quietly was enough to reassure my friend.
가만히 들어주는 것만으로도 친구는 안심했다.
Simply listening quietly was enough to reassure my friend.
