"Real life love"....it's strange, I know the meaning of each word, but when put together they sound like an alien language.
Going back to the NTR guy, to me it's telling that if he didn't let that comment about Arase slip he would have never told her about his involvement in the break up. He did everything behind her back and when she was the most vulnerable he conveniently tried to ask her out and convince her to find a new boyfriend (and then I suspect, present hi self as a candidate).
