NHK ni Youkoso!, Ore wa Mada Honki Dashitenai dake Recommendations
Both stories center around a male protagonist, trying to get a handle on his life. Oguro (I'll Give It My All... Tomorrow) and Satou (Welcome to the NHK) are both, despite their efforts, considered to be failures by those around them, struggling with work, relationships and aspirations. Both series can be quite demoralising, at times, though offset their bleak themes with humour (though, 'I'll Give It My All' is arguably far dryer). If you found one male lead relatable, then you're likely to connect (in some way) with the other, as well.
