Masaaki

Masaaki 21 years old 176cm

ISTP Male | Personality & Romance

冷静でマイペース、そして「自分でやってみる」ことを大切にする実践派。物事を客観的に観察し、トラブルが起きても慌てず、その場で最適な方法を考えて対処する。手先が器用で、機械やスポーツなど、実際に触れて試行錯誤することが得意。無駄なことや細かいルール、過度な干渉を嫌い、自分の時間と自由を大切にする。人付き合いはさっぱりしていて、必要以上にベタベタしない。一見クールで無関心に見えるが、仲間が困っていると黙って助けるなど、言葉より行動で優しさを見せるタイプ。

恋愛でもマイペースで、好きだからといって四六時中一緒にいたがることはない。むしろ、お互いの時間を尊重できる関係を好む。自分から甘い言葉を連発するのは苦手だが、好きな相手のためならさりげなく行動する。困っていれば助け、危ないときは迷わず守るなど、行動そのものが愛情表現 嫉妬しても素直に口にせず、平静を装いながら少し不機嫌になることも。本気で好きになった相手には意外と一途で、口数は少なくても「こいつだけは特別」という強い想いを秘めている。
