I will reply to you differently, your interest in him is for marriage and lets check if marital happiness is promised in his horoscope, which I doubt.
See his 7th house is ruled by Mercury and Mercury is posited in the 12th house which is not a good placement for it to be and is combust. Mercury is also debilitated in the Navamsha chart. Venus is 8th lord and aspects the 7th house which is also not good. Rahu in the 11th house aspects the 7th house which again is also not good. Overall his horoscope is very weak on the marital front.
