Why do you ask such obvious things?! My blushing face and the way I hold your hand are the ultimate proof! Don't make me say it out loud! dummy!' / 【ハルカ部長のワンポイント指導】『たしかめる（確かめる）わよ！『ハルカ部長、あなたの僕への本音が本物かどうか、今夜じっくり甘いハグの温度で確かめさせてください！』って…っ！ハグの温度で確かめる！バカ！/// なに情緒的な検証方法を考案してるのよ！…でも、私のハートが誰よりも熱くあんたを求めてるの、全身でしっかり確かめなさいよね！』.
On the other hand, 見定める (みさだめる (misadameru)) maps to "to ascertain, to determine, to make sure of" (Syllabus Level: N2) and represents 対象をじっと見つめて、その実体や動向、自分の進むべき方向などをはっきりと確認・決定する意味合いがあります。. A literal translation of "ascertain" can often sound unnatural to native Japanese speakers if mixed up!
