Another loser author who would have guessed. Dating for a long time, known each other since children still afraid to even kiss. Yeah really realistic. Can't wait for the author to get bored with this manga give us the kiss and then the ending chapter which will be either a wedding or just a timeskip with their married life. Good luck if you continue to follow this chapter by chapter, I'm stopping until chapter 100(if the author doesn't get bored until then).
