Explanation (EN): The phrase 「～反面」(はんめん) means \"on the other hand\" or \"while.\" It is used to present a contrasting or opposite aspect of the same thing or situation that was just mentioned. It attaches to nouns (with 「である」), な-adjectives (with 「な/である」), い-adjectives (plain form), or verbs (plain form). It's often used for objective descriptions of a single subject with different attributes. Example: この薬はよく効く**反面**、副作用も強いので注意が必要だ。\n\nCommon Mistakes:\n❌ に対して: We use 'に対して' for contrasting TWO DIFFERENT subjects (e.g., dogs vs. cats). Since we are talking about the pros and cons of the EXACT SAME medicine, '反面' is correct!\n❌ に比べて: You can't compare the medicine's effectiveness... to itself! Use '反面' to show its two faces.\n❌ ばかりか: 'ばかりか' means 'not only A, but also B'. However, it usually connects things of the SAME polarity (two good things, or two bad things). Since 'highly effective' (Good) and 'strong side effects' (Bad) are opposites, use '反面'!
